ABSTRACT:
An infrared imaging system uses an uncooled elliptical surface section between reflective surfaces to allow a detector to perceive a cold interior of a vacuum chamber rather than a warmer surface of a structure or housing. In this way, background infrared radiation from within the system may be minimized.
