Definition of bolometer in English: bolometernoun bəˈlɒmɪtəbəˈlɑmədər A sensitive electrical instrument for measuring radiant energy. Example sentencesExamples - Antenna-coupled bolometers commonly achieve time responses of 100 nanoseconds, with shorter times possible depending upon the thermal isolation of the sensor element.
- 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.
- On the thermal side are thermocouples, thermopiles, bolometers, and pneumatic detectors.
- 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.
- 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.
Derivatives adjectivebəʊləˈmɛtrɪk The bolometric detector is achieved by means of technologies used in the semiconductor field. Example sentencesExamples - It is known that due to the bolometric effect dipole excitation of electrons can effectively heat the 2DES and change its resistance.
- Does the bolometric correction account for this emission?
- Just as in conventional bolometric sensors, joule heating raises the temperature of the structure, causing a resistance change that is sensed externally.
- It includes a set of 52 bolometric detectors, which work by converting radiation to heat.
