ABSTRACT:
A thermal energy receiver is disclosed comprising a cooling means for cooling an infrared detector including a detector array for producing electrical representations of thermal energy radiating from a scene and an array of cold shields providing an individual cold shield aperture for substantially shielding each detector element of the array from energy generated outside the solid angle subtended by the optical elements, and electro-optics for converting the electrical output of the detector array to visual signals for displaying the scene.
