摘要： A parallel optical information processing system includes an information inputting part which produces a coherent optical beam spatially modulated by input image information. A rewritable hologram memory carries a plurality of stored images as holograms so that the holograms are overlapped with each other, the rewritable hologram memory being written with image information when illuminated by a recording optical beam. An image reproducing part is supplied with the input image information, and produces reproduced image information from the rewritable hologram memory. A hologram synthesizing part synthesizes a synthetic hologram in response to the reproduced image information. A hologram recording part records the synthetic hologram in the rewritable hologram memory through the recording optical beam.
