General line of sight stabilization system

A line of sight stabilization system using two mirrors pivotally mounted to a fixed platform that can be used with existing imaging systems to provide pitch, roll, and yaw compensation while maintaining image orientation. By deflecting only the photons, the inventive system avoids the need to stabilize the entire imaging sensor and optics system. The only mass to move is that of the two imaging system mirrors. By monitoring attitude changes via an inertial measurement system, proceeding platform positions can be estimated for subsequent image acquisitions, and efficient mirror positioning can provide optimal image orientation and stabilization. This approach requires small motors with low torque, providing a less expensive, lightweight, and small image orientation and stabilization system.

Method of framing reconnaissance with motion roll compensation

An electro-optical roll-framing camera is described in which successive overlapping frames of scene imagery are generated by an electro-optical imaging array. 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 during the generation of the frames of imagery. The successive frames of imagery are made during a continuous roll motion of the entire camera (including the array). The image motion due to roll is stopped or frozen without mechanically stopping the roll motion, such as found in prior art step frame cameras. The roll framing cycles of the camera generate sweeping coverage of the terrain of interest. The roll rate for a given electro-optical array is a function of the frame size and the framing rate, and is controllable by a master camera control computer.
