Abstract

A tunable laser rangefinder having a wavelength tunable transmitter output and a wavelength tunable receiver that matches the transmitter wavelength. The transmitter provides laser energy output pulses that are reflected off a target and received by the receiver. The time between the transmitter pulse and the receiver pulse is determined and the range of the target is calculated. The transmitter and receiver frequencies are changed from pulse to pulse to provide good countermeasure immunity. In a preferred embodiment the rangefinder uses a solid state, reliable cobalt magnesium fluoride laser to provide laser energy in a region of the infrared spectrum which is eye safe and has good atmospheric transmission.
