Paper Abstract

The 300K background limit is routinely achieved by cryogenic LWIR photon detectors such as Hg0.795Cd0.205Te operating at 77K. Will uncooled thermal detectors be able to do so? It appears that only resistive bolometers can. The necessary steps are described. The state-of-the-art of VOX and a-Si bolometers are compared with theory.
