How does a bolometer work
WebNov 9, 2024 · A two-dimensional array of photo-detectors is used to sense the incident light intensity. The charge created by a photo-detector is converted to a voltage signal and passed on to the output amplifier through an array of “row select” and “column select” switches. An ADC is used to digitize the amplified signal. 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 …
