Abstract
An optical system that records images that travel through a turbulent atmosphere to a camera on a moving platform is designed to sense image distortions in a first segment of the image and to apply a set of correction signals to a segment of a deformable mirror that corresponds to the portion of the image that is detected. In a closed-loop embodiment, the corrected subimage is followed across the aperture, with successive corrections being applied sequentially to each of a set of segments at the time when that segment is reflecting the subimage in question. Consecutive subimages follow the same procedure. Corrected subimages are reflected off the deformable mirror to a detector array. At intervals, a frame's worth of data may be read out of the detectors and stored.
