El uso de series de televisión para la formación de competencias en Psicoterapia / The use of television series in the formation of psychotherapeutic competences

Introducción: La formación de competencias en Psicoterapia es una tarea difícil, que exige continuamente la evaluación de nuevos métodos que complementen los tradicionales. Objetivo: Evaluar el uso de series de televisión en la formación de competencias para identificar y modelar procedimientos psicoterapéuticos como alternativa a los métodos tradicionales. Métodos: Estudio de caso (n = 24) en el contexto de un diplomado de intervención clínica psicodinámica: grupo experimental (n = 12) y grupo de control (n = 12). En el grupo experimental se usaron, como complemento, series de televisión relacionadas con la Psicoterapia, editadas en fragmentos con entradas diferenciadas por marcadores asociados a conceptos clave. Resultados: El uso de tecnologías audiovisuales en la formación de competencias terapéuticas, como complemento a la enseñanza tradicional, no pareció modificar las habilidades teóricas de los alumnos; sin embargo, favoreció los resultados en las evaluaciones de competencias prácticas en Psicoterapia. También mejoró la visión de proceso y la capacidad para evaluar situaciones; desarrolló capacidades para la aplicación oportuna de herramientas terapéuticas; diversificó el repertorio conductual ante situaciones inesperadas; y pareció mejorar la disposición afectiva para enfrentar los primeros casos. Conclusiones: La incorporación de series de televisión como complemento didáctico en un programa de Psicoterapia parece mejorar la efectividad del proceso enseñanza-aprendizaje. El estudio también sugiere que el uso de este tipo de herramientas técnicas de la tecnología de la información, como un método complementario, favorecerá la preparación emocional de los profesionales en formación para trabajar con los primeros pacientes de Salud Mental; sin embargo, esta hipótesis deberá corroborarse en futuras investigaciones que incluyan una muestra mayor(AU)

Introduction: The formation of psychotherapy competences is a difficult task, which demands permanent assessment of new methods complementing the traditional ones. Objective: To assess the use of television series in the formation of competences to identify and model psychotherapeutic procedures, as an alternative over traditional methods. Methods: Case study, with n=24, carried out in the context of a diploma course in Clinical Psychodynamic Intervention. There was an experimental group (n=12) and a control group (n = 12). In the experimental group, television series related to psychotherapy were used as complementary ones, edited in fragments with entries differentiated by markers associated with key concepts. Results: The use of audiovisual technologies in the formation of therapeutic competences, as a complement to traditional teaching, did not seem to modify the theoretical abilities of the students; however, it favored the outcomes in the assessment of practical psychotherapeutic competencies. It also improved process vision and the ability to assess situations, developed capacities for timely application of therapeutic tools, diversified the behavioral repertoire in unexpected situations, and seemed to improve affective disposition to face the first cases. Conclusions: The incorporation of television series as a didactic complement in a psychotherapy program seems to improve the effectiveness of the teaching-learning process. The study also suggests that the use of this type of technical information technology tools, as a complementary method, will favor the emotional preparation of professionals under training to work with their first mental health patients; however, this hypothesis should be corroborated in future research including a larger sample(AU)

Interventions to control children's screen use and their effect on sleep: A systematic review and meta-analysis.

Prolonged viewing of screen-based media is associated with poor sleep in children. Previous systematic reviews have analysed the effectiveness of interventions that aim to limit children's screen use; however, none have evaluated its effect on sleep. The aim of this systematic review was to evaluate the effect of interventions that incorporate strategies to control children's screen use on screen use and sleep. The databases Pubmed, Embase, Eric, Scopus and PsycInfo were searched during October 2017 and updated in February 2019 for experimental studies with a control that assessed interventions to control screen use in children aged 2-14 years and reported both screen use and sleep outcomes. From 3,872 initial records, 11 studies (six randomized control [RCT], four cluster RCT and one cluster, quasi-experimental) were eligible for inclusion. A total of 4,656 children aged 2-13 years were included in the studies. The mean reduction in screen time was 0.56 hr (33 min)/day (95% confidence interval [CI], 0.92, 0.20) and the mean sleep duration increased by 0.19 hr (11 min)/day (95% CI, 0.05, 0.33). Bedtime was advanced by 0.16 hr (10 min) on weekdays and by 1.0 hr at the weekend. Subgroup analyses indicated stronger intervention effects for interventions of shorter duration (<3 months), which specifically targeted screen use or sleep, and those with direct participant contact. In conclusion, small improvements in screen time and sleep duration can be achieved in children. It is not possible to determine if a reduction in screen time directly improves sleep, due to the limited number of studies, the presence of co-interventions, issues with studies' methodological quality and heterogeneity.

[Asessment of television food marketing for children according to Ministry of Health nutrition profile guidelines]. / Ulusal yayin yapan bazi uluslararasi çocuk televizyon kanallarinda çocuklara yönelik gida ve içecek reklamlarinin Saglik Bakanligi besin profili rehberine göre degerlendirilmesi.

Obesity is a growing problem in infants, children, and adolescents in our country and all over the world. Obese children usually remain obese in their adulthood and they are risk of chronic diseases. In our country, » (24.5%) of 2nd grade students in primary school, approximately 1/3 (30.1%) of middle school students and 1/5 (20.6%) of high school students are obese/overweight. This study was conducted to evaluate TV advertising of these products according to the Healthy Nutrition and Active Life Program of the Turkish Ministry of Health, which is based on World Health Organization recommendations. It was observed that there were numerous inappropriate increased number and time food and beverage advertisements broadcast during programming directed at children. Monitoring and evaluation of mechanisms should be founded according to the 27.03.2018 regulation about Broadcast Service Procedures and Principles initiated by Radio and Television Supreme Council (RTÜK). It is important to encourage healthy habits and take measures to prevent chronic diseases such as obesity in childhood.

Cell phone and technology use by octogenarians.

INTRODUCTION Many countries, including New Zealand, have an aging population and new technologies such as cell phones may be useful for older people. AIM To examine cell phone and technology use by octogenarians. METHODS Te Puawaitanga O Nga Tapuwae Kia Ora Tonu- Life and Living in Advanced Age: A Cohort Study In New Zealand (LILACs NZ) cohort study data of Maori (aged 80-90 years, 11-year age band) and non-Maori (aged 85 years, 1-year age band) followed for 3 years was used to describe the prevalence among study participants of the use of the internet, cell phones and watching pay-per-view television. Association of these activities with living arrangement, congestive heart failure, chronic obstructive respiratory disease and participants' cognition were examined. RESULTS Technology use was relatively low among study octogenarians. Fewer Maori used cell phones and the internet (16% and 6%) than non-Maori (30% and 19%). Maori participants supported only by a pension were less likely to use cell phones than Maori with more income. More men watched pay-per-view television (e.g. SKY) than women. Living alone and having chronic lung disease were associated with not watching pay-per-view television. Participants who used the internet had higher cognition scores than others. Non-Maori women were less likely to watch pay-per-view television and non-Maori on a pension only were less likely to watch pay-per-view television than people on a higher income. Participants who lived alone were less likely to watch pay-per-view. CONCLUSION Relatively low use of technology may limit potential for health technology innovation for people of advanced age. Socioeconomic and ethnic disparities will amplify this.

Publicidade de Géneros alimentares no meio Televisivo em Moçambique / Food advertising in the media Television in Mozambique

Nos dias que correm, tem-se assistido a mudanças "drásticas" no padrão alimentar e nutricional da população, e a televisão é apontada como um dos grandes factores que contribui para essas mudanças. Com objectivo principal de avaliar a frequência com que a publicidade sobre alimentos é veiculada nos canais de televisão moçambicanos, o presente estudo, do tipo transversal (qualitativo-quantitativo), registou todas publicidades transmitidas por canal durante um mês, das 7h-12h no meio de semana e das 17h-22h, no final-de-semana. Do total de publicidades registadas, 20,6% eram de géneros alimentares na sua maioria com densidade energética, ricos em açúcar, sal e pobres em nutrientes. Vericou-se ainda que apenas 21,6% dos alimentos publicitados são integrantes da nova roda de alimentos, sendo os anunciantes dominantes a e Coca-Cola Company, Tropigália, KFC, Cadbury e Cervejas de Moçambique (CDM).

There has been a drastic change in the population's food and nutritional environment, and the television is pointed out as one of the major contributing factors for this remarkable zchange. Aiming to assess the frequency in which food commercials are advertised in the Mozambican television channels, a mixed-method cross-sectional study, recorded all advertising broadcast during the hours from 7h AM-12PM and 5h-10 PM, one working day a week and weekend in a month per channel. Out of total advertising registered, 20.6% were of foods mostly with caloric density, high in sugar, salt and low in nutrients. Of this, only 21.6% of the foods advertised were part of the new food trend and the most dominant advertisers were e Coca-Cola Company, Tropigália, KFC, Cadbury and Cervejas de Moçambique (CDM).

Getting Your Grumble Back.

PURPOSE OF STUDY: Viewing the surgical patient holistically within their environment of care, the bedside nurse is aware of the possible complication of postoperative paralytic ileus that can lead to patient discomfort and increased medical costs. Acute care nurses observed postoperative patients watching televised cooking shows on a consistent basis and questioned if there was a mind-body link between bowel function and watching cooking shows. DESIGN OF STUDY: The study used an observational approach to examine the return of bowel sounds for postoperative patients. METHOD: Ninety-four patients that underwent abdominal surgery participated. A questionnaire was administered to capture total hours postsurgery of patient viewing cooking shows followed by chart review for age, height, weight, information specific to surgery, and documented first postsurgical flatus. FINDINGS: This study found that non-bariatric general surgery patients who watch cooking shows during hospitalization are significantly more likely to experience return of appetite and stomach sounds within 1 day postsurgery than patients who do not watch cooking shows. CONCLUSIONS: Based on the results of this study, the authors suggest that, when possible, patients who receive non-bariatric abdominal surgery be encouraged to watch cooking shows to experience the potential benefits such as early return of bowel functioning.

Electromagnetic Field Exposure Changes Due to the Digital Television Switchover in Thessaloniki, Greece.

In the present work, the changes in the exposure to electromagnetic fields due to television signals incurred by the digital switchover in Thessaloniki, Greece, are investigated. It is shown that the measured electric fields comply with ICNIRP guidelines but are higher than those in the reported literature for other countries. However, this may be attributed to the selection of measurement points. Moreover, it is shown that the median value of the power density dropped from 60 µW m during analog broadcasting to 13.3 µW m for digital television. This finding indicates that the digital switchover has resulted in reduced exposure for the population to radiofrequency fields in the UHF range.

Global responses for recycling waste CRTs in e-waste.

The management of used cathode ray tube (CRT) devices is a major problem worldwide due to rapid uptake of the technology and early obsolescence of CRT devices, which is considered an environment hazard if disposed improperly. Previously, their production has grown in step with computer and television demand but later on with rapid technological innovation; TVs and computer screens has been replaced by new products such as Liquid Crystal Displays (LCDs) and Plasma Display Panel (PDPs). This change creates a large volume of waste stream of obsolete CRTs waste in developed countries and developing countries will be becoming major CRTs waste producers in the upcoming years. We studied that there is also high level of trans-boundary movement of these devices as second-hand electronic equipment into developing countries in an attempt to bridge the 'digital divide'. Moreover, the current global production of e-waste is estimated to be '41million tonnes per year' where a major part of the e-waste stream consists of CRT devices. This review article provides a concise overview of world's current CRTs waste scenario, namely magnitude of the demand and processing, current disposal and recycling operations.

Measuring treatment costs of typical waste electrical and electronic equipment: A pre-research for Chinese policy making.

Waste Electrical and Electronic Equipment (WEEE) volume is increasing, worldwide. In 2011, the Chinese government issued new regulations on WEEE recycling and disposal, establishing a WEEE treatment subsidy funded by a levy on producers of electrical and electronic equipment. In order to evaluate WEEE recycling treatment costs and revenue possibilities under the new regulations, and to propose suggestions for cost-effective WEEE management, a comprehensive revenue-expenditure model (REM), were established for this study, including 7 types of costs, 4 types of fees, and one type of revenue. Since TV sets dominated the volume of WEEE treated from 2013 to 2014, with a contribution rate of 87.3%, TV sets were taken as a representative case. Results showed that the treatment cost varied from 46.4RMB/unit to 82.5RMB/unit, with a treatment quantity of 130,000 units to 1,200,000 units per year in China. Collection cost accounted for the largest portion (about 70.0%), while taxes and fees (about 11.0 %) and labor cost (about 7.0 %) contributed less. The average costs for disposal, sales, and taxes had no influence on treatment quantity (TQ). TQ might have an adverse effect on average labor and management costs; while average collection and purchase fees, and financing costs, would vary with purchase price, and the average sales fees and taxes would vary with the sales of dismantled materials and other recycled products. Recycling enterprises could reduce their costs by setting up online and offline collection platforms, cooperating with individual collectors, creating door-to-door collection channels, improving production efficiency and reducing administrative expenditures. The government could provide economic incentives-such as subsidies, low-cost loans, tax cuts and credits-and could also raise public awareness of waste management and environmental protection, in order to capture some of the WEEE currently discarded into the general waste stream. Foreign companies with advanced WEEE utilization technology could invest or participate in this area, producing profits for themselves while helping to develop and implement environmentally friendly and energy-saving technologies applicable to the Chinese market.

High-quality collection and disposal of WEEE: Environmental impacts and resultant issues.

Life cycle assessment of the collection, transport and recycling of various types of waste electrical and electronic equipment (WEEE) in Norway shows that small amounts of critical materials (refrigerants, precious/trace metals) are vital for the overall environmental accounts of the value chains. High-quality recycling ensures that materials and energy are effectively recovered from WEEE. This recovery means that responsible waste handling confers net environmental benefits in terms of global warming potential (GWP), for all types of WEEE analysed. For refrigeration equipment, the potential reduction of GWP by high-quality recycling is so large as to be of national significance. For all waste types, the magnitude of the net benefit from recovering materials and energy exceeds the negative consequences of irresponsible disposal. One outcome of this may be widespread misunderstanding of the need for recycling. Furthermore, framing public communication on recycling in terms of avoiding negative consequences, as is essentially universal, may not convey an appropriate message. The issue is particularly important where the consumer regards products as relatively disposable and environmentally benign, and/or where the "null option" of retaining the product at end-of-life is especially prevalent. The paper highlights the implications of all these issues for policy-makers, waste collectors and recyclers, and consumers.

Using TV white space spectrum to practise telemedicine: A promising technology to enhance broadband internet connectivity within healthcare facilities in rural regions of developing countries.

The following correspondence provides an overview of TV White Space (TVWS) technology, regulations, and potential applications to the health care sector. This report also introduces "Project Kgolagano," a Botswana-based initiative representing the first endeavour to utilize TVWS internet connection for practising telemedicine. TV "white space" refers to the previously unused, wasted spectrum within TV radiofrequency channels that can now be leveraged to obtain broadband internet access. TVWS represents a less costly, faster, and farther-reaching internet connection that is a promising option for connecting the previously unconnected populations of remote and underserved areas. The Botswana-University of Pennsylvania Partnership, Microsoft, Botswana Innovation Hub, Vista Life Sciences, and Global Broadband Solutions have partnered together to bring TVWS wireless broadband access to healthcare facilities in poorly connected regions of Botswana (Lobatse, Francistown, Maun, Gaborone) in order to improve healthcare delivery and facilitate telemedicine in dermatology, cervical cancer screening, and family medicine (HIV/AIDS, TB, general adult and pediatric medicine).

EEG-based usability assessment of 3D shutter glasses.

OBJECTIVE: Neurotechnology can contribute to the usability assessment of products by providing objective measures of neural workload and can uncover usability impediments that are not consciously perceived by test persons. In this study, the neural processing effort imposed on the viewer of 3D television by shutter glasses was quantified as a function of shutter frequency. In particular, we sought to determine the critical shutter frequency at which the 'neural flicker' vanishes, such that visual fatigue due to this additional neural effort can be prevented by increasing the frequency of the system. APPROACH: Twenty-three participants viewed an image through 3D shutter glasses, while multichannel electroencephalogram (EEG) was recorded. In total ten shutter frequencies were employed, selected individually for each participant to cover the range below, at and above the threshold of flicker perception. The source of the neural flicker correlate was extracted using independent component analysis and the flicker impact on the visual cortex was quantified by decoding the state of the shutter from the EEG. MAIN RESULT: Effects of the shutter glasses were traced in the EEG up to around 67 Hz-about 20 Hz over the flicker perception threshold-and vanished at the subsequent frequency level of 77 Hz. SIGNIFICANCE: The impact of the shutter glasses on the visual cortex can be detected by neurotechnology even when a flicker is not reported by the participants. Potential impact. Increasing the shutter frequency from the usual 50 Hz or 60 Hz to 77 Hz reduces the risk of visual fatigue and thus improves shutter-glass-based 3D usability.

Crisis reflejas, cine y televisión / Reflex seizures, cinema and television

En el cine y las series de televisión existen escasas referencias a las crisis o epilepsia refleja, a pesar de que en la vida real constituyen un subgrupo relevante del total de síndromes epilépticos. Se ha realizado una búsqueda sobre el tema y se han identificado 25 documentos cinematográficos en los que aparecen crisis reflejas. La mayoría de las crisis observadas son tonicoclónicas generalizadas y los estímulos visuales son los más numerosos, y todos se corresponden con destellos luminosos. Entre los estímulos por procesos de nivel superior destacan las emociones. En la mayoría de las ocasiones no es posible saber si el personaje padece una epilepsia refleja o bien sufre crisis reflejas en el contexto de otro síndrome epiléptico. La principal conclusión es que, en el cine y la televisión, las crisis reflejas no son más que un elemento visual de refuerzo y anecdótico, sin incidencia relevante en la trama argumental (AU)

In movies and television series are few references to seizures or reflex epilepsy even though in real life are an important subgroup of total epileptic syndromes. It has performed a search on the topic, identified 25 films in which they appear reflex seizures. Most seizures observed are tonic-clonic and visual stimuli are the most numerous, corresponding all with flashing lights. The emotions are the main stimuli in higher level processes. In most cases it is not possible to know if a character suffers a reflex epilepsy or suffer reflex seizures in the context of another epileptic syndrome. The main conclusion is that, in the movies, the reflex seizures are merely a visual reinforcing and anecdotal element without significant influence on the plot (AU)

Out with the old, out with the new--The effect of transitions in TVs and monitors technology on consumption and WEEE generation in Sweden 1996-2014.

The recycling of Waste Electrical and Electronic Equipment (WEEE) is important due to its content of valuable and hazardous compounds. This study investigates the case of the recent technology change within television sets (TVs) and monitors, its impact on the generation of WEEE, and the implications for the recycling industry. In particular, material flow analysis for the time series of 1996-2014 for TVs and monitors by type of technology (CRT, Plasma and LCD) in physical units is combined with empirical data on product lifespans. The number of consumed TVs and monitors has grown exponentially. As a result, despite a 3-fold reduction in the weight of the products, the weight of the corresponding WEEE is also growing exponentially. Out with the old, out with the new - a peak in WEEE from both CRT and flat-screen displays is expected during 2014-2020, due to the simultaneous obsolesce of the last wave of CRT products and the short-lived flat-screen products that substituted the CRTs. The lifespans of LCD and LED TVs were found to be three times shorter than of the CRT TVs, with many TVs discarded while still functional. This is the consequence of two events - replacement of the CRT TVs in combination with lifestyle purchases of TVs, i.e. the premature replacement of flat-screen displays with new sets with extra-large screens and/or new features. The throughput of TVs and monitors consumed has been estimated annually from 2014 until 2040, by quantity and type of device, as well as by component and material type. The annual economic value of the corresponding secondary materials, by material type, has also been estimated. The point in time when the final disposal of CRT products is likely to take place has been identified and should be noted by the recycling industry. Among the important contributions of this study to the accounting and predicting of amounts and types of WEEE are the lifespan distributions, size and weight distributions, and material composition for TVs and monitors of different technology. Directions for method application in other countries are given.

Deficiencia, discapacidad, neurología y series de televisión / Deficiency, disability, neurology and television series

Introducción. El enfoque de la deficiencia y la discapacidad neurológica en la televisión no ha sido algo unívoco, sino que ha reflejado la postura de la sociedad ante estas cuestiones y cómo se tratan éstas, desde la óptica de las concepciones y valores dominantes en cada momento. Objetivos. Abordar la aparición de la patología neurológica en las series de televisión y reflexionar sobre su imagen en dicho contexto. Desarrollo. La deficiencia y la discapacidad de origen neurológico se han reflejado ampliamente en el medio televisivo en series, telefilmes y documentales, con un tratamiento desigual. Se aborda el enfoque que ha tenido en diferentes series televisivas la patología neurológica, su diagnóstico, su tratamiento, así como la figura de los profesionales sanitarios y la adaptación socio-familiar, y se citan, a modo de ejemplo, series como House, Glee, American Horror Story, Homeland o Juego de tronos. Conclusiones. Las series de televisión son una herramienta útil para dar a conocer algunas patologías neurológicas y para desmitificar otras, siempre que dichas patologías se aborden de manera realista, hecho que no siempre ocurre. Habría que cuidar el tratamiento que reciben los profesionales de la salud en las series de televisión, pues no siempre es correcto, y eso puede llevar a errores entre los telespectadores, que aceptan lo que ven en la pequeña pantalla como real (AU)

Introduction. The portrayal of neurological disability and defi ciency on television has not always been approached in the same way, but has instead tended to refl ect the standpoint taken by society with regard to these issues and how they are dealt with according to the prevailing conceptions and values at each particular time. Aims. To address the appearance of neurological pathologies in television series and to ponder on the image they have in such contexts. Development. Defi ciency and disability of neurological origin have often been depicted on television in series, telefilms and documentaries, and in a wide variety of ways. Here we examine diff erent television series and how they have dealt with neurological pathology, its diagnosis and its treatment, as well as the figure of the healthcare professional and social-familial adaptation. Examples cited include series such as House MD, Glee, American Horror Story, Homeland or Game of Thrones. Conclusions. Television series are a useful tool for making some neurological pathologies better known to the public and for dispelling the myths surrounding others, provided that the pathologies are dealt with in a realistic manner, which is not always the case. More care should be taken with regard to the way in which health professionals are portrayed in television series, as it is not always done correctly and may mislead viewers, who take what they see on the TV as being real (AU)

Two men with advanced amyotrophic lateral sclerosis operate a computer-aided television system through mouth or throat microswitches.

This study assessed a simple technology to enable two men affected by amyotrophic lateral sclerosis, in an advanced stage (i.e., with pervasive motor disabilities and lack of speech), to operate a computer-aided television system. The technology included microswitches, a portable computer, an interface connecting the microswitches to the computer, a commercial software package to allow the possibility of watching television via computer, and specific software to allow microswitch activations to be recorded as forward commands for channel change. The participants (a) gained control over the television programs to watch or not to watch (i.e., through channel changes) and (b) showed increased attention to the programs (i.e., an increase in their watching time). The practical relevance of the findings, the integration of the technology used in this study within the participants' wider recreation and communication program, and ways of extending the research were discussed.

User experience while viewing stereoscopic 3D television.

3D display technologies have been linked to visual discomfort and fatigue. In a lab-based study with a between-subjects design, 433 viewers aged from 4 to 82 years watched the same movie in either 2D or stereo 3D (S3D), and subjectively reported on a range of aspects of their viewing experience. Our results suggest that a minority of viewers, around 14%, experience adverse effects due to viewing S3D, mainly headache and eyestrain. A control experiment where participants viewed 2D content through 3D glasses suggests that around 8% may report adverse effects which are not due directly to viewing S3D, but instead are due to the glasses or to negative preconceptions about S3D (the 'nocebo effect'). Women were slightly more likely than men to report adverse effects with S3D. We could not detect any link between pre-existing eye conditions or low stereoacuity and the likelihood of experiencing adverse effects with S3D.

Reduction-melting combined with a Na2CO3 flux recycling process for lead recovery from cathode ray tube funnel glass.

With large quantity of flux (Na2CO3), lead can be recovered from the funnel glass of waste cathode-ray tubes via reduction-melting at 1000°C. To reduce flux cost, a technique to recover added flux from the generated oxide phase is also important in order to recycle the flux recovered from the reduction-melting process. In this study, the phase separation of sodium and the crystallization of water-soluble sodium silicates were induced after the reduction-melting process to enhance the leachability of sodium in the oxide phase and to extract the sodium from the phase for the recovery of Na2CO3 as flux. A reductive atmosphere promoted the phase separation and crystallization, and the leachability of sodium from the oxide phase was enhanced. The optimum temperature and treatment time for increasing the leachability were 700°C and 2h, respectively. After treatment, more than 90% of the sodium in the oxide phase was extracted in water. NaHCO3 can be recovered by carbonization of the solution containing sodium ions using carbon dioxide gas, decomposed to Na2CO3 at 50°C and recycled for use in the reduction-melting process.

Multiwavefront digital holographic television.

This paper presents the full technology chain supporting wide angle digital holographic television from holographic capture of real world objects/scenes to holographic display with an extended viewing angle. The data are captured with multiple CCD cameras located around an object. The display system is based on multiple tilted spatial light modulators (SLMs) arranged in a circular configuration. The capture-display system is linked by a holographic data processing module, which allows for significant decoupling of the capture and display systems. The presented experimental results, based on the reconstruction of real world, variable in time scenes, illustrates imaging dynamics, viewing angle and quality.
