  • Measurement Of Optical Distance (AREA)

Abstract

PURPOSE: To correctly detect the distance with the use of a simple construction by receiving the incident light in a photometric area of two optical system, which are arranged at a distance corresponding to a base line of an automatic focusing system of a camera, with the use of two photoelectric converting elements, each of which is composed of a single light receiving element, to detect the coincidence of the optical information.
