Abstract: A wide-field-of-view (WFOV) optical system includes a negative optical-power primary mirror configured to receive and reflect light from an image scene; a low optical-power secondary mirror configured to receive and reflect light from the primary mirror; a negative optical-power tertiary mirror configured to receive and reflect light from the secondary mirror; and a positive optical-power quaternary mirror configured to receive and reflect light from the tertiary mirror. The primary, secondary, tertiary and quaternary mirrors are configured to maintain an effective focal length (EFL) at edges of the field of view (FOV) of the optical system to be at least equal to a center of the FOV of the optical system so that a spatial resolution of the optical system essentially remains constant across the FOV.

Abstract: Various embodiments provide an optical system including a plurality of mirrors, each mirror having a rotational axis of symmetry; and a detector configured to detect an image formed by the plurality of mirrors. The plurality of mirrors are configured to scan an object space along a first direction. The plurality of mirrors are configured and arranged so that a focal length of the plurality of mirrors along the first direction is greater than a focal length of the plurality of mirrors in a second direction perpendicular to the first direction so as to obtain a ratio of anamorphism greater than approximately 1.5.

Abstract: Various embodiments provide an optical system including a first lens group including a plurality of lenses, the first lens group being configured to correct for lateral chromatic aberration; and a second lens group including a plurality of lenses, the second lens group being configured to correct for axial chromatic aberration, the second lens group being disposed adjacent the first lens group. The optical system further includes a detector disposed behind the second lens group; a mechanism for switching a configuration of the optical system between a narrow field of view (NFOV) configuration and a wide field of view (WFOV) configuration; and a ray path steering system disposed in front of the first lens group, the ray path steering system comprising a pair of counter-rotating grisms configured to enhance a field of regard of the optical system. The optical system also includes a stabilization system configured to suppress image jitter, the stabilization system including a mechanism for decentering at least one lens in the first lens group or in the second lens group orthogonal to an optical axis of the optical system. A pupil of the optical system is located external to the first and second lens groups for location of a cold shield within a cryo-vac Dewar enclosing the detector.
