ABSTRACT:
In the disclosed distance measuring system, a light measuring circuit measures light reflected from an object whose distance is to be measured. An output arrangement responds to the light measuring circuit by producing an output in the form of a signal representing a distance to an object. A device widens the scanning range of the distance measuring system when the object is more difficult to observe than usual.
