Abstract

Very few possibilities are referred to give a solution to the problem of holographic television. We mean here holographic being any system capable of bringing images in continuous horizontal parallax. Occlusion is a necessary property for representing objects with realm, as opaque elements instead oftransparent ones. The only system we know that satisfies this requirements is being developed by Benton since 1989. It consists in processing the object information by Fourier transformation by very powerful parallel computing processing introducing this information in one crystal electrooptical modulator by means of acoustic waves while reading it by means of a laser. Color can be obtained by making a three-chromatic RGB system. The computer simulated images are, to our knowledge, well defmed in continuous horizontal parallax . It was recently reported 2 to have reached the size 8.5cm (V) x 13cm (H) x 20 cm3. We proposed a white light system capable of generating a vectorially addressed holo-like image This system was further developed recently to generate a sequence of TV planes where reach TV frame is seen oblique to a holographic screen, traversing it from its front to his back. A controlled mirror makes this plane to fill a volume by scanning along the screen, so that if we project a sequence of contour lines of an object it can be seen in continuous horizontal parallax, to a size of 1m3, up to now. First results using computer generated models will be described. The system has the possibility of occiussion by control of the spectral distribution when encoding each point, a development to reach in future work.
