Laser Safety Evaluation of the Oscmar M203PI Grenade Launcher Simulator (GLS) and the Associated Umpire Control Gun

摘要

The Oscmar M203PI Grenade Launcher Simulator (GLS) is designed to simulate the M203PI,40-mm Grenade Launcher mated to the M16 rifle or to a pistol grip used in engagement simulation system (ESS) force-on-force exercises. It uses an infrared (IR) laser diode with optics to simulate the wide area effect of an exploding 40-mm grenade. The unit consists of the M203PI Large Area Transmitter (LAT) and a M203PI Dummy Round (DR). The M203 is a breach-loaded weapon. The LAT is installed inside the M203 PI Grenade Launcher Tube (GLT) and is affixed to the exit end with a securing ring. The DR is loaded like a real round. The DR emits an IR signal, from a light emitting diode (LED) when the firing pin strikes the center of the DR base plate. The LAT initiates a fire sequence upon receiving a signal, through the IR link, from the DR. The LAT emits a series of laser pulses (coded output). The LAT may also emit laser pulses by the initiation of Auto Align or Auto Fire mode directive from the Umpire Gun and will continue to emit until directed to stop by the Umpire Gun.
