Abstract

In an example, a thermal imaging test article comprises a block configured to be attached to a blackbody on a back side of the block, the block having a variable thickness to represent facial features of a human face, the block including a cutout to allow a thermal imaging device to see the blackbody behind the block through the cutout, and one or more heaters thermally coupled to the block to produce heat to heat the block. The variable thickness of the block and the heat produced by the one or more heaters are selected to simulate thermally the human face on a front side of the block.
