Abstract (en)
[origin: WO0219030A1] An electro-optical roll-framing camera (36) is described in which successive overlapping frames of scene imagery (1-5) are generated by an electro-optical imaging array (300). Image motion compensation is performed electronically to stop or freeze image motion caused by the roll motion. The image motion compensation is performed by the array (64) during the generation of the frames of imagery (1-5). The successive frames of imagery (1-5) are made during a continuous roll motion of the entire camera. The image motion due to roll is stopped or frozen without mechanically stopping the roll motion. The roll framing cycles (1-5) of the camera generate sweeping coverage of the terrain of interest (42). The roll rate for a given electro-optical array (300) is a function of the frame size and the framing rate, and is controllable by a master control computer (34). A novel catoptric Cassegrain optical system (50) which performs forward motion compensation is also described.
