ABSTRACT:
An infrared (IR) radiation detector adapted to detect IR radiation by measuring pneumatic expansion of a sense chamber that is caused by a temperature increase within that chamber due to the absorbed energy of the IR radiation. A reference chamber mechanically coupled to the sense chamber controls the pneumatic expansion of the sense-chamber. The expansion is detected either electrically or optically.
