Abstract

The 300K background limit is routinely achieved by cryogenic LWIR photon detectors such as Hg_0.795Cd_0.205Te 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 VO_X and a-Si bolometers are compared with theory.
