  • Solar cell detector array for engagement simulation
    Patent number: 3950862
    Abstract: This invention relates to a multi-solar cell detection arrangement for detection of pulsed laser radiation inside a military helmet. Each solar cell is coupled to a ferrite core which allows operation in full sunlight without the need of optical filters. The solar cells are activated by short-pulsed laser radiation, directed from a laser transmitter such as an injection laser transmitter mounted on an M-16 rifle and bore-sighted with a rifle sight so as to simulate rifle fire.
