Abstract

PURPOSE: To find two-dimensional position coordinates of an object by providing two image pickup systems, by arranging their mirrors at two points at a constant distance, and by finding a couple of estimated angles from those two points to the object.
CONSTITUTION: This device consists of plane type photodetectors 8 and 9 consisting of even-numbered photodetecting parts with the same photodetecting area, a detecting circuit that detects an image being in the centers of those photodetecting surfaces, rotary scanning mirrors 1 and 2 for scanning an object, and detector mirror- rotation for 10. When the image of object 15 is positioned in the centers of image pickup surfaces of photodetectors 8 and 9, rotation angles of mirrors 1 and 2 are detected with signals from detector 10 and the photodetectors. From distance L between axes P1 and P2 of rotation of mirrors 1 and 2 and rotation angles θ1/2 and θ2/2 of mirrors 1 and 2, distance (a) between P1 and center P3 of object 15 is calculated by a microcomputer to find its two-dimensional position.
