单词 bolometer
释义

Definition of bolometer in English:

bolometer

noun bəˈlɒmɪtəbəˈlɑmədər
  • A sensitive electrical instrument for measuring radiant energy.

    辐射热测定器

    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

  • bolometric

  • 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.
  • bolometry

  • noun

Origin

Late 19th century: from Greek bolē 'ray of light' + -meter.
