Is there anybody on the forum who is up to speed with the ins and outs of these devices?
99% of research papers and all manufacturers comment I have read say these devices are working because the distant object emits radiation that the detector absorbs and therefore this absorbed energy *heats* the detector. In fact these devices seem to be radiatively coupled to the observed scene in a two way energy exchange and are either heated or they are cooled by the observed scene depending upon its temperature.
Is there though some peculiar property of these devices that enables the detector to always only be heated?
