ABSTRACT
The experimental evaluation of a transparent electrophotographic (TEP) film is reported. The objective of the evaluation was to determine the suitability of TEP films for optical data storage applications, especially those using holography. The characteristics of TEP films that motivated the evaluation are good sensitometric and holographic recording responses, relatively high resolution, and a number of attractive applications properties, e.g., long shelf life, good environmental integrity, and exceptional image permanence. In addition, TEP films have an add-on capability. A general description of TEP films is given, and sensitometric and holographic data are summarized for an experimental TEP film.
ABSTRACT
The experimental evaluation of a new heat-processed photoresist is reported with reference to holographic data storage applications. Two attractive features of the photoresist are (1) holographic reconstruction parameters comparable to the best photographic emulsions and (2) orthochromatic exposure sensitivity optimized for the 488-nm line of an argon laser. The preparation, use, and general properties of the photoresist are discussed, and relevant experimental data for important holographic parameters such as diffraction efficiency and storage density are presented.
