One of the mysteries of the English language finally explained.
A sensitive electrical instrument for measuring radiant energy.
- ‘Antenna-coupled bolometers commonly achieve time responses of 100 nanoseconds, with shorter times possible depending upon the thermal isolation of the sensor element.’
- ‘On the thermal side are thermocouples, thermopiles, bolometers, and pneumatic detectors.’
- ‘Stephan S. Meyer of the University of Chicago will develop a frequency - selective bolometer to study dusty galaxies in the early universe from a balloon-borne telescope over Antarctica.’
- ‘The radiometer measured light intensity by the number of revolutions induced over time, and the bolometer measured a decrease in electrical resistance upon absorption of radiation.’
- ‘During a routine check for contamination in their bolometers, which happen to be built around crystals containing bismuth, the team noticed an unexpected alpha decay not listed in any reference tables.’
Late 19th century: from Greek bolē ‘ray of light’ + -meter.
