Method of and device for detecting light receiving position utilizing optical fibers

摘要

A method of detecting light receiving position utilizing optical fibers comprising: a plurality of light receiving surfaces each of which is formed by end surfaces of a plurality of optical fibers arranged straight, and which are arranged in parallel with each other to form rows which are divided into groups to form output ports; light receiving sensors each of which is formed by one light detection device, and which are connected to the corresponding groups, whereby laser beams from the light receiving surfaces are detected by the light receiving sensors through the optical fibers.
