Abstract: An imaging platform minimizes image distortion when there is relative motion of the imaging platform with respect to the scene being imaged where the imaging platform may be particularly susceptible to distortion when it is configured with a wide field of view or high angular rate of movement, or when performing long-stares at a given scene (e.g., for nighttime and low-light imaging.) Distortion correction may be performed by predicting distortion due to the relative motion of the imaging platform, determining optical transformations to prevent the distortion, dynamically adjusting the optics of the imaging platform during exposure, and performing digital image correction.

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.
