  • Weapon effect simulators
    Patent number: 4373916
    Abstract: In a weapon effect simulator a low peak power laser projector emits one millisecond bursts of radiation, each burst having either pulse or continuous wave modulation at 170 kHz. A detector for sensing the radiation has several photocells connected in parallel to a single amplifier, and includes a band pass filter tuned to 170 kHz (chosen in harmonic relationship to the modulation frequency) and having a pass band of 2 kHz (inversely related to the duration of each radiation burst).
