Bolometer
Rendition of an imaging bolometer from Los Alamos National Laboratory
A bolometer is a device for measuring incident electromagnetic radiation. It was invented in 1878 by the American astronomer Samuel Pierpont Langley.
Bolometer. An instrument used to measure heat radiation.

CCD. Charge Coupled Device. An electronic device used in place of conventional photographic film.
Bolometer
(a) An instrument for measuring small amounts of radiant heat or microwaves. It depends on the change in resistance of a piece of metal foil or a superconductor when it absorbs radiant energy.
BOLOMETER
A bolometer is an instrument that measures the total amount of radiant energy (not just visible light) received from a star or other celestial object.

bologram The record obtained from a bolometer. bolometer An instrument which measures the intensity of radiant energy by employing a thermally sensitive electrical resistor; a type of actinometer. Also called actinic balance .
Langley devised his bolometer, which was a much more sensitive instrument than the thermopile, he, in conjunction with F. W. Very, applied it to determine the moon's radiation at the Allegheny observatory.
A major breakthrough came in 1961, with the development of the germanium bolometer. This instrument was hundreds of times more sensitive than previous detectors and was capable of detecting all infrared wavelengths.
The TES instrument encompasses three measurement channels: A spectrometer, a bolometer or radiance channel, and a reflectance or albedo channel. The spectrometer is a Michelson interferometer with six fields of view, each with 3 km resolution.
On July 6, 2004, a team of astronomers (including Jane Greaves, Mark Wyatt, Wayne Holland, and William Dent) using the Submillimetre Common-User Bolometer Array (SCUBA) of the James Clerk Maxwell Telescope at the Joint Astronomy Center on the Big ...
Planck employs both HEMT radiometers as well as bolometer technology and will measure the CMB on smaller scales than WMAP. Unlike the previous two space missions, Planck is a collaboration between NASA and ESA (the European Space Agency).

Langley invented the bolometer, a highly sensitive electrical device for measuring temperature. Solar heat and energy are measured by an instrument called the pyrheliometer.
Instruments for detecting infrared radiation include heat-sensitive devices such as thermocouple detectors, bolometers (some of these are cooled to temperatures close to absolute zero so that the thermal radiation of the detector system itself is ...
The survey was conducted by an international team of astronomers using the LABOCA camera (Large APEX Bolometer Camera) on the Atacama Pathfinder Experiment (APEX) telescope in Chile and has resulted in the largest map of cold dust ever produced at ...
It was the only telescope to operate at these frequencies in the southern hemisphere. Its 37-channel hexagonal bolometer array, SIMBA (Sest IMaging Bolometer Array), operated at a wavelength of 1.2 mm.
1 K and signals are being received from the bolometers. This is similar to the startup of WMAP, which took a slower route to L2 but did not need to be as cold. WMAP made its first data release 587 days after launch.
⇒ Its observations are made with the spectroscope, bolometer, etc., usually in connection with the telescope.
