ABSTRACT:
A laser ranging system which includes a laser pulse emitter, an imaging and impingement detecting amplifier and a system processor is provided. The laser pulse emitter produces a pulse of light to be reflected by at least one object at an unknown distance from the laser emitter. The detecting sensor has a multiplicity of photoelements and collects reflected light from the object. The detecting sensor determines the intensity of the reflected light and the time it first impinged on each of the photoelements. The system processor controls the laser pulse emitter and the detecting sensor. The system processor also receives output from the detecting sensor to produce at least distance indications for the object based on the length of time from emission of the pulse of light to receipt of its reflection as sensed by each of the photoelements.
