Paper Abstract

In the face of the increasing need to be able to process two-dimensionally organized data, the present electronic digital processing and coherent optical data processing techniques have proven inadequate. The potential advantage of coherent optical data processing (CODP) is that, as opposed to the serially organized electronic digital computers, it can simultaneously process data on a very large number of parallel channels. The limitation to the usefulness of CODP has been the lack of a high-speed, high-spatial-bandwidth input device. This paper describes the development of a new CODP input device capable of the required speed and spatial bandwidth. The device employs an integral CCD input to accept serial electronic signals and a liquid-crystal light valve output for CODP.
