How does a bolometer work
Webradiometer, instrument for detecting or measuring radiant energy. The term is applied in particular to devices used to measure infrared radiation. Radiometers are of various types that differ in their method of measurement or detection. Those that function by means of an increase in the temperature of the device, such as Herschel’s thermometer, are called … WebBolometer. In a basic sense, a bolometer is a simple sensor that absorbs thermal radiation, and changes resistance as a result. This change in resistance can be electrically …
