Radiation detector with remote temperature reference
Description
A radiation detector is described comprising: a thermopile having a hot junction and a cold junction, the thermopile sensing radiation emitted from a target and providing an output signal indicative of a temperature of the target; and a thermocouple having a hot junction and a cold junction, one of said thermocouple junctions being thermally remote from the hot and cold junctions of the thermopile, the thermocouple being electrically connected in series with the thermopile in a passive circuit and providing an output signal which combines with the output signal of the thermopile to produce a total output signal, a change in the thermocouple output signal with a local temperature being inversely related to a change in the thermopile output signal with said local temperature
