ABSTRACT
The paper considers the present stage of development and ways of improving TV endoscopes for medicine. It has been shown that the most promising are the TV endoscopes which have sequential colour-separated transmission circuit and include impulse R, G, B light sources. The light is transferred through fibre optical conduit and matrices installed at the distal end of the endoscope. Digital converters convert the colour-separated image signals into simultaneous ones. This circuit makes it possible to avoid using expensive and complex equipment in manufacture of fibre optics. It provides a suitable for diagnosis image quality which can be additionally improved by electronic treatment of the image signal.

Various fields of the holographic methods application in medico-biological investigations are discussed. Special consideration is given to the methods of holographic interferometry, holographic microscopy, ultrasonic holography and to the technique of optic filtration of images. The paper sets forth brief characteristics of diverse holographic methods, technical possibilities of each one of them and a review of some practical work done in this field.
