Abstract:
A staring infrared imaging sensor comprising:a primary lens disposed to accept infrared radiation and to project therefrom a Field Of Regard (FOR) image onto a primary image plane; a plurality of primary mirrors disposed at the primary image plane each for reflecting a corresponding portion of the FOR image along a corresponding one of a plurality of optical paths; a secondary lens disposed within each optical path to focus the corresponding FOR image portion onto a corresponding secondary image plane within the corresponding optical path; a secondary mirror disposed at the corresponding secondary image plane within each optical path to reflect the corresponding FOR image portion along one of a corresponding plurality of preselected directions; an image detector disposed at a tertiary image plane for generating an electronic signal representing an image projected onto the tertiary image plane; and a tertiary lens disposed within each optical path to focus the corresponding FOR image portion onto the tertiary image plane.
