The apparatus is a thermal detector which uses an active detector element and a compensator detector element, particularly in a voltage divider configuration. Radiation from a scene of interest impinges on the active detector element and radiation from an electronically modulated light source impinges on the compensator detector element.

Thermal detector modulation scheme

An infrared detector capable of obtaining coincident fields of view of infrared radiation of different wavelengths is provided. The detector comprises a sandwich-type construction including PbSe and PbS photoconductive film layers.
