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. 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.
