WebInfrared detectors employ modern technologies for detecting spectral regions that are not visible to the eyes. They are used for thermal imaging in many fields, including buildings, public services, and science. While most detectors can emit and receive infrared waves in the form of heat, some can only receive infrared waves. WebAn infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many … somalia water crisisWebInfrared thermometers work based on a phenomenon called black body radiation. Anything at a temperature above absolute zero has molecules inside of it moving around. The higher the temperature, the faster the molecules move. As they move, the molecules emit infrared radiation--a type of electromagnetic radiation below the visible spectrum of light. somalia web hosting

"WebAn optical gas imaging camera can be considered a highly specialized version of an infrared or thermal imaging camera.
