REDUCTION IN THE RECONSTRUCTION ERROR COMPUTER-GENERATED HOLOGRAMS BYPHOTOREFRACTIVE VOLUME HOLOGRAPHY

We suggest a method for coding high-resolution computer-generated volu me holograms. It involves splitting the computer-generated hologram in to multiple holograms, their individual recording as volume holograms by use of the maximal resolution available from the spatial light modu lator, and subsequent simultaneous reconstruction. We demonstrate the recording and the reconstruction of a computer-generated volume hologr am with a space-bandwidth product much higher than the limitation impo sed by the interfacing spatial light modulator. Finally, we analyze th e scheduling procedure of the multiple holographic recording process i n photorefractive medium in this specific application.
