Abstract

A constituent unit for an optical information processing system comprises an input information displaying device, which one-dimensionally, two-dimensionally, or three-dimensionally displays presented information as an optical pattern. Each of optical correlation operation devices located close to the input information displaying device detects only an optical pattern falling within a predetermined range among the optical pattern displayed on the input information displaying device, and carries out an optical correlation operation in order to calculate correlation between information representing the detected optical pattern and predetermined information having been stored in each optical correlation operation device. Each optical correlation operation device thereafter feeds out the results of the correlation operation. Each of electric operation devices receives the results of the correlation operation from a predetermined number of the optical correlation operation devices, carries out a predetermined operation on the results of the correlation operation, and feeds out the results of the predetermined operation.
