ABSTRACT:
A test system (10) for a laser rangefinder (12, 14) having signal transmission and reception paths comprises a thick lens collimator (20) which receives energy (18) from a transmitter (12) for input through an optical fiber (32). The fiber has a partial reflector (34) and a full reflector (38) to simulate sites of targets, and the reflected energy is transmitted back through collimator (20) to a receiver (14). Partial reflection of energy is provided by gold (64) placed on a surface (53) of one of two aligned and spaced termini (32a, 32b) of fiber (32).
