摘要
An infrared detector system is provided for detecting infrared radiation from an infrared radiation source or a scene. The system includes a first area that is semiconductor-based and biased to produce negative luminescence, the first area including at least one semiconductor-based detector. The detector system further includes at least one additional area being semiconductor-based and biased to produce negative luminescence. A low-emissivity specular retro-reflector shield is configured to reflect infrared radiation and covers the first area and the at least one additional area. The shield defines an aperture to allow the at least one semiconductor-based detector to receive incident rays of the infrared radiation from the infrared radiation source or the scene via a low-scatter, low-emission optical system such that the radiation incident from the infrared radiation source or scene substantially fills the solid angle defined by the aperture at any point in the first area.
