Abstract

An optical device is employed for information processing operations such as pattern recognition, image display and information storage. The optical device comprises a body in which a number of spot-like transparent sections are arranged in the form of a matrix on a main surface thereof or a number of linear transparent sections are arranged in parallel to one another on the same, a plurality of transparent sections being arranged on the end surface thereof in correspondence to the lines and/or the columns of the above-described transparent section, and beam introducing paths, namely, beam guide means, such as optical fibers, which are provided in the body, for optically connecting the transparent sections on the main surface to the respective ones on the end surface. This optical device is utilized in such a manner that photosensitive elements or luminous elements are connected directly to the transparent sections on the end surface or are connected through an optical encoder or an optical decoder indirectly to the same.

Dependent claims

An information processing optical device which comprises:

a body having on a major surface thereof a number of discrete spot-like beam input sections arranged in the form of a matrix, and beam output sections in first and second groups with said groups arranged on separate end surfaces of the body in correspondence with the lines and columns of the spot-like beam input sections;
beam guide means of a material different than said body provided in the body for each individually optically connecting corresponding individual beam input sections with both a corresponding one of the output sections in the first group and a corresponding one in the second group and including beam-dividing means comprising means having reflecting surfaces integral therewith for separating and independently transmitting individual beam input signals of radiant energy from the discrete, spot-like beam input sections in the lines and columns of said matrix to the beam output sections in the first and second groups as two independent beams representative of directions representative of X and Y directions for specifying the position of the corresponding individual input beams in X and Y coordinates;
first and second optical encoders provided respectively in correspondence to the individual beam output sections in the first and second groups;
and beam input terminals on the optical encoders optically connected to the respective beam output sections in the first and second groups.
