And, like all sensors, their performance cannot exceed that of an ideal device of their class; fundamental limits exist which cons

Recently it has been discovered that thermal detectors have been in use for perhaps millions of years in target locating systems by two families of snake who use the temperature difference between their prey and its surroundings to locate and capture the small animals on which they feed (. and .

Photovoltaic and Photoconductive Infrared Detectors,though they must often be cooled to achieve such performance. Their performance is high and continues to improve because of the development of highly purified, single-crystal semiconductors as their active materials. However, several different materials appear to be competing for dominance, and it i
