ELECTRO-OPTICAL IMAGING DETECTOR ARRAY WITH TWO AXIS IMAGE MOTION COMPENSATION

摘要

An electro-optical imaging array (32) having pixels arranged in rows and columns electronically compensates for image motion in the plane of the arra y regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of r ow and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft (22) about roll (R), pitch (PI ) and/or yaw (Y) angles in addition to forward velocity (V) of the aircraft (22). The image motion compensation is achieved with no moving parts and doe s not require a stabilized platform. The pixel information in the array (32) i s transferred in the row and column direction in a step-wise fashion in the ro w and column directions at a rate and direction substantially matching the ima ge motion.
