| Reduction in the reconstruction error of computer-generated holograms by photorefractive volume holography (1993) | |||||||||||||
Abstract | |||||||||||||
| We suggest a method for coding high-resolution computer-generated volume holograms. It involves splitting the computer-generated hologram into multiple holograms, their individual recording as volume holograms by use of the maximal resolution available from the spatial light modulator, and subsequent simultaneous reconstruction. We demonstrate the recording and the reconstruction of a computer-generated volume hologram with a space-bandwidth product much higher than the limitation imposed by the interfacing spatial light modulator. Finally, we analyze the scheduling procedure of the multiple holographic recording process in photorefractive medium in this specific application. Binary computer-generated holograms (CGH's) are becoming essential components in optical signalprocessing schemes. Apart from their use as a means for storage and reconstruction of images, these holograms can serve as spatial filters, optical elements, and the basic component in interconnection networks. CGH's are created in an electronic computer and are displayed on spatial light modulators | |||||||||||||
