ABSTRACT:
Here is disclosed an optical gauging apparatus utilizing light reflected on an object to be gauged and being useful for gauging of, for example, car level, spring deflection and photographic distance. Light emitted from a single light source is split into a pair of light components propagated along a pair of optical paths, respectively, the light components thus split are projected along different optical path lengths onto the object, at least one of the light components is intermittently shielded and the light components reflected on the object are photoelectrically converted to the corresponding photoelectric conversion signals which are then time-division processed so as to provide a desired gauging information.
