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 … WebA bolometer consists of a radiation absorber connected to a thermal reservoir (a body of constant temperature) through a thermal conductor. The radiation on the absorber raises its temperature above that of the reservoir: The greater the radiation intensity, the more energy the absorber absorbs, and the higher its temperature rises.
WebOct 9, 2013 · A bolometer is a highly sensitive instrument used for detecting heat or electromagnetic radiation. This instrument was invented by Samuel Pierpont Langley, an American astronomer, in 1878. A bolometer was initially used in combination with a telescope to quantify infrared radiation. The first bolometer used by Langley consisted of … Webbolometer, instrument for measuring radiation by means of the rise in temperature of a blackened metal strip in one of the arms of a resistance bridge.
