WebApr 23, 2009 · Bolometer, an instrument used to measure infrared, or heat, radiation. The bolometer is essentially a very sensitive thermometer. It can be used with a spectroscope … Metal bolometers usually work without cooling. 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. See more 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 See more The first bolometers made by Langley consisted of two steel, platinum, or palladium foil strips covered with lampblack. … See more The term bolometer is also used in particle physics to designate an unconventional particle detector. They use the same principle described … See more The hot electron bolometer (HEB) operates at cryogenic temperatures, typically within a few degrees of absolute zero. … See more A bolometer consists of an absorptive element, such as a thin layer of metal, connected to a thermal reservoir (a body of constant … See more 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. For sub-millimeter wavelengths through millimeter wavelengths (from around 200 µm to a … See more A microbolometer is a specific type of bolometer used as a detector in a thermal camera. It is a grid of vanadium oxide or amorphous silicon heat sensors atop a corresponding grid of silicon. Infrared radiation from a specific range of wavelengths strikes … See more
