More Information
Summary:A multispectral thermal infrared camera system is disclosed. An uncooled thermal imaging camera is equipped with an axially tilted, cooled spectral filter. The axially tilted, cooled spectral filter deflects the radiation emitted by the uncooled camera away from being reflected back into the camera. The axially tilted, cooled spectral filter emits a lesser amount of thermal radiation towards the camera. And the axially tilted, cooled tilted filter is enclosed in a cold radiation shield to minimize the thermal emission that would be reflected by the filter towards the camera and to absorb the radiation deflected by the tilted filter. The axially tilted, cooled spectral filter passes only the desired portion of the thermal infrared radiation from the scene onto the uncooled camera.
