Abstract
For many military applications small, lightweight range finders are required that operate at a high pulse repetition rate. It will be shown that a ranging system with an injection laser in the transmitter can fulfill these requirements. The performance of an optical ranging system employing a pulsed gallium arsenide laser diode transmitter, with peak powers up to 100 watts at room temperature is described. After a brief review of fundamental system parameters, calculations of the range capability of the system are given, based upon the Poisson distribution of photoelectron statistics. A discussion is presented on the experimental support of theoretical analysis.Keywords
