How does a bolometer work

WebA bolometer consists of a radiation absorber connected to a thermal reservoir (a body of constant temperature) through a thermal conductor. The radiation on the absorber raises its temperature above that of the reservoir: The greater the radiation intensity, the more energy the absorber absorbs, and the higher its temperature rises. WebA bolometer (or calorimeter) is a detector for radiation or particles. … A bolometer works by measuring this change of T with a thermometer which is directly attached to the absorber. …
