Paper Abstract

The paper gives an overview on 3D television which can be realized by a number of methods: stereoscopy, autostereoscopy, integral imaging, volumetric display, and digital holography where digital holograms - recorded or computed - are fed to spatial light modulators (SLM). All methods have their specific advantages and disadvantages, which can be reduced parallax, lacking motion parallax, limited lateral resolution, occlusion problem, or the severe accomodation conflict, causing eye fatigue and other discomforts. By principle holography exhibits none of these imperfections, but the problem of the necessary high space-bandwidth-product is the main obstacle for its introduction for 3D TV up to now. The needed high space-bandwidth-product requires CCDs and SLMs with higher number of pixels, a shorter pixel pitch, and faster computers than available today. Here we present first solutions to the space-bandwidth-product problem, e. g. by restricting on horizontal parallax only, by using eye-trackers resulting in calculation of only the observed small parts of the hologram, by employing image plane holography instead of Fresnel- or Fraunhofer-holography, or by using a proper combination of electrically together with optically addressable SLMs.
