How a bolometer works
WebAnswer (1 of 3): Wiki: A bolometer is a device for measuring the power of incident electromagnetic radiation via the heating of a material with a temperature-dependent electrical resistance. Now, let's go through it in detail. A bolometer is a very sensitive thermometer that is used to calculate... WebHow does a bolometer work? A bolometer (or calorimeter) is a detector for radiation or particles. … A bolometer works by measuring this change of T with a thermometer which is directly attached to the absorber. As a thermometer one commonly uses a material which changes strongly in resistivity with temperature in the regime of interest.

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 …

They are produced from thin foils or metal films. Today, most bolometers use semiconductor or superconductor absorptive elements rather than metals. These devices can be operated at cryogenic temperatures, enabling significantly greater sensitivity. Ver mais A bolometer is a device for measuring radiant heat by means of a material having a temperature-dependent electrical resistance. It was invented in 1878 by the American astronomer Samuel Pierpont Langley Ver mais The first bolometers made by Langley consisted of two steel, platinum, or palladium foil strips covered with lampblack. One strip was … Ver mais The term bolometer is also used in particle physics to designate an unconventional particle detector. They use the same principle described above. The bolometers are sensitive not … Ver mais The hot electron bolometer (HEB) operates at cryogenic temperatures, typically within a few degrees of absolute zero. At these very low temperatures, the electron system in a metal is weakly coupled to the phonon system. Power coupled to the … Ver mais A bolometer consists of an absorptive element, such as a thin layer of metal, connected to a thermal reservoir (a body of constant temperature) through a thermal link. The result is that any radiation impinging on the absorptive element raises its … Ver mais While bolometers can be used to measure radiation of any frequency, for most wavelength ranges there are other methods of detection that are more sensitive.
