摘要： A laser weapon simulator apparatus for practice in the shooting of a firearm at a target having reflective material thereon. The apparatus includes a laser beam transmitter that is actuable to emit a laser beam of short duration, a laser beam receiver for collecting and processing a reflected portion of the laser beam, circuitry for detecting the emission of the laser beam by the transmitter, and a visual display. The receiver includes circuitry adapted to produce a "hit" signal upon receiving the reflected portion of the laser beam and the detecting circuitry is adapted to produce a "try" signal in response to the emission of the laser beam. The visual display produces an output "hit" display signal upon the concurrent receipt of a "hit" signal from the receiver and a "try" signal from the detecting circuitry.
