ABSTRACT:
A device for optically displaying thermal image scenes, comprising pneumatic infrared sensors, for example, temperature-sensitive gas cells. A mosaic of thermal IR sensors, which is arranged on an infrared-transparent plate and which picks up the thermal image scene, is arranged in front of a reference plate whose inclination can be adjusted and which is irradiated by optical light. The interference patterns produced are picked up by an optical system. Thermal drift is suppressed by providing the IR sensors in a hermetically sealed chamber.
