Infrared Detectors
Infrared detectors are devices that are used to detect and measure infrared radiation. Infrared radiation is a type of electromagnetic radiation that has a longer wavelength than visible light, and is typically emitted by objects that are at a higher temperature than their surroundings. Infrared detectors are used in a wide range of applications, including thermal imaging, remote sensing, and spectroscopy. There are several different types of infrared detectors, each of which operates on a different principle. One common type is the thermal detector, which measures the temperature of an object by detecting the infrared radiation that it emits. Another type is the photodetector, which uses a semiconductor material to convert incoming infrared radiation into an electrical signal. Infrared detectors are used in a wide range of applications, including military and civilian surveillance, medical imaging, and industrial process control. They are also used in astronomy to study the infrared radiation emitted by celestial objects.
