Abstract

PURPOSE:To obtain a device which is small-sized and high in accuracy, by constituting so that an output of PSD by an optical image of a body to be photographed, which has formed an image through a semitransparent mirror is compared with an output of PSD by an optical image through a moving mirror which has been placed so as to have a base line length to the semitransparent mirror. CONSTITUTION:A light beam from a body to be photographed 0 forms an image on PSD31 through a semitransparent mirror 32 and a lens 1, and its output is stored in a storing circuit 35 through a position detecting and processing circuit 34, and a contact M of a switch SW1. Subsequently, a douser 33 is saved from the position for intercepting a light beam from a moving mirror 4, intercepts a light beam transmitted through the semitransparent mirror 32, and also changes over the switch SW1. The moving mirror 4 starts to turn, and a light beam reflected by the moving mirror 4 forms an image in the PSD31. Its output is inputted to a comparator through the circuit 34, is compared with an output of the storing circuit 35, and when its difference output is ''0'', a distance D0 is derived. In this way, a device which is small-sized and high in accuracy is obtained.
