ABSTRACT:
A laser range meter utilizing a mode locked laser for transmitting ultrashort pulses toward a target and a receiver for cross correlating the pulses returned from a target with corresponding reference pulses derived from the transmitted pulses is disclosed. Cross correlation is accomplished with a nonlinear element which responds to the return and reference pulses by producing secondary radiation of longer duration and of an intensity indicative of the time correlation of the pulses. The secondary radiation is sensed with a photodetector whose output signal is supplied to an output device.
