摘要： An optical system for infrared detection in the 3 to 14 micrometer region comprising: a viewing aspheric corrector, a spherical mirror having a focal length, said spherical mirror being positioned to receive the light passed by said viewing aspheric corrector, a plurality of detector cells comprising an array thereof sufficient to vertically scan an image to provide high resolution and positioned to lie at the focal length of said optical system behind a narrow pass spectral filter, said detector cells being adapted to produce an electrical signal responsive to the infrared radiation detected thereby, means for moving the system field of view in azimuth, a multiplexer to scan the array of cells and deliver their signals sequentially to an image display, and a cryogenic cooling system for cooling the filter and the cells.
