Abstract: In a system that includes a wire grid polarizer, the polarizer is positioned between a thermal illuminator and a thermal emitter such that energy from the thermal illuminator traveling towards the thermal emitter is transformed into linearly polarized energy. In the system, the thermal emitter is configured to reflect at least a portion of the linearly polarized energy towards a millimeter-wave camera and there is a motor coupled with the wire grid polarizer and configured to rotate the polarizer in a manner that varies an apparent temperature of the thermal emitter based on the reflected portion of the linearly polarized energy.

Abstract: In a system having a thermal backdrop (106) and a thermal illuminator (102), the thermal backdrop includes a body having a top face; a contrast phantom (114) positioned above the top face and aligned substantially parallel with the top face; and a reflective layer (112) located between the body and the contrast phantom and aligned substantially parallel with the top face. The thermal illuminator radiates thermal energy (104) in a first direction towards the contrast phantom; wherein the first direction is aligned with the top face such that when the thermal energy is radiated in the first direction a first portion of the thermal energy is absorbed by the contrast phantom and a second portion (116) is reflected by the reflective layer towards a millimeter-wave camera (118) in a second direction. Furthermore, the contrast phantom has a plurality of different portions (114A, 114B, 114C, 114D), each portion having a different respective thickness along the first direction.
