Abstract: A pyroelectric detector assembly for detection of 10.6 .mu.m infrared laser radiation which has a thin film detector element fabricated from thin film lithium tantalate (LiTaO.sub.3) coated with black gold, and an ultra low noise charge coupled preamplifier optimized for lithium tantalate. A postamplifier includes a low pass filter, voltage comparator, threshold adjustment, and pulse generator.

Abstract: A transmitter and receiver for "MILES" type systems is in a pistol type configuration, and is provided with a display, to indicate the mode of the controller unit, as well as the specific MILES codes which are transmitted or received. The versatile unit is particularly flexible in its ability to test the various components of Multiple Integrated Laser Engagement System, with "MILES" being the acronym for these combat training exercise systems. A continuous rotary control switch determines the mode, either (1) transmit, (2) receive, or (3) identity change. In the transmit mode, rotation of the switch will change the transmitted MILES code, and actuation of the trigger switch will transmit the MILES code and an associated identity code. In the identity change mode, operating the trigger switch will change the I.D. number of the "player". In the receive mode, the display will show the received MILES code, and the player identity number.

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.
