  • Bolometers are used for the measurement of Thermal radiations.
  • Bolometers are devices that are designed to measure the change in temperature of a material as a result of absorbing electromagnetic radiation, including thermal radiation.
  • Bolometers work by measuring changes in the electrical resistance of a material that is sensitive to changes in temperature.
  • When electromagnetic radiation is absorbed by the material, it causes an increase in the temperature of the material, which in turn causes a change in its electrical resistance.
  • By measuring this change in resistance, bolometers can provide an accurate measurement of the amount of radiation absorbed.
  • Bolometers are commonly used in a wide range of applications, including astronomy, materials science, and environmental monitoring, among others.
  • In astronomy, bolometers are used to measure the intensity of infrared radiation emitted by stars and galaxies.
  • In materials science, bolometers can be used to measure the thermal conductivity and specific heat of materials. In environmental monitoring, bolometers can be used to measure the temperature of the Earth's surface and to monitor climate change.
