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