Abstract :
A promising approach to 3D-TV is the concept of digital holography. One way is to record the interference pattern which is generated by superposition of the wave field reflected from the scene and a mutually coherent reference wave by a CCD-or CMOS-array, transmitting the data, and displaying the wave field by feeding the data to a spatial light modulator which is illuminated with coherent light. Another way is to perform a numerical reconstruction and to transmit and display the reconstructed 3D-data by a non-holographic method. Both these ways require an analysis of their limits and of the reconstruction algorithms before a practical implementation of digital holographic methods for 3D-TV is started. Conservative estimates of the limits rest on the sampling theorem while recent results have shown that reliable reconstructions are also possible even with sub-sampling for moderate boundary conditions. Here the preliminaries of an all-digital-holographic approach to 3D-TV are given and some implications are discussed.
