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.
