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.

摘要： An optical disc system typically includes an optical disc and an optical pick-up for projecting a light beam for recording information. The optical pick-up or at least its objective lens is provided to be movable relative to the optical disc in a predetermined direction. The optical pick-up uses two light beams, one of which is for recording information on the disc and the other of which is for reproducing the information recorded on the disc immediately after it has been recorded for confirmation. In accordance with the present invention, it is so structured that a tracking error of the confirmation light beam on the disc is monitored and the light intensity of the confirmation light beam emitted from the light source is varied in accordance with the detected tracking error of the confirmation light beam on the disc.
