ABSTRACT:
A distance measuring device has a light emitter, a light receiver including a plurality of photoresponsive elements for sensing the pulsating light beam emitted by the light emitter and subsequently reflected from a target object relative to which the distance from the device is to be measured, and a signal processing circuit. The signal processing circuit includes a logic circuit so designed as to determine the significance of an output signal from one of a number of light measuring circuits connected to the respective photoresponsive elements in relation to output signals from the other of the light measuring circuits.
