Photoemissive Detectors,etection. These are 1) the detection of low-intensity signals, either weak in total available power or diffuse at the optical focal plane; 2) high-speed detection of low-level signals; and 3) the acquisition of high resolution spatial information (imaging) [5.1 – 4].

Photovoltaic and Photoconductive Infrared Detectors,purified, single-crystal semiconductors as their active materials. However, several different materials appear to be competing for dominance, and it is not clear whether photovoltaic or photoconductive effects should be emphasized. We shall attempt to put the situation into better perspective.

Thermal Detectors,r array along their jaws. It has now been established that the snakes’ sensors are in fact thermal detectors (. and . [3.2,3]). Although it has been suggested that some moths and other insects employ infrared techniques, this has not so far been confirmed. The snakes therefore appear to have been the first to develop thermal infrared detectors.
