https://doi.org/10.1351/goldbook.B00694
A
detector
constructed from a material having a large temperature
coefficient
of
resistance
. Absorption of radiation gives rise to a change in
resistance
. A bolometer is named according to its active component, e.g. thermistor bolometer,
semiconductor
bolometer, superconductor bolometer.
