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.

Pyroelectric hybridized long-wave infrared laser radiation detector

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. The light emitting output from the unit may be a light-emitting diode or a laser and the detector may be a hybrid amplifier/detector, including a photodiode and an amplifier, provided with a plastic cover serving both as protection for the diode and also as a filter. The unit may be provided with a buzzer to indicate the receipt of a MILES code signal.
