Infrared detector is a kind of radiant energy converter. It is mainly used to convert the received infrared radiant energy into various forms of erroneous alarm system for measuring or observing electric energy, heat energy and other forms of energy. According to the energy conversion method, Infrared detectors can be divided into two categories: heat detectors and photon detectors. The working mechanism of heat detectors is based on the thermal effect of incident radiation, which causes changes in a certain electrical characteristic of the detector. The photon detector is based on incident photon flow and detection. The photoelectric effect produced by the interaction of materials is manifested by the change in the number of free carriers (ie, electrons and/or holes) in the detector response. Since this change is caused by a change in the number of incident photons, the photon detector The response is proportional to the number of absorbed photons. The response of the heat detector is proportional to the absorbed energy.
