Abstract
An optical radar system includes an optical transmitter which responds to a drive signal to radiate a search light pulse into detection fields arranged in the direction in which the vehicle is moving. An optical receiver includes a plurality of arrayed photoelectric sensitive elements which receive any search light pulses reflected by objects in the detection fields. A distance measuring device determines the respective distances from the system to the objects and the corresponding directions in which the objects lie in accordance with the delay between the drive signal and the reception of the corresponding reflected search light pulses by the individual photoelectric elements.
