Abstract:
1. A system comprising: an optical assembly configured to receive electromagnetic radiation emitted by a target and produce an image of said target; a focal plane array, said focal plane array being configured to receive said image and integrate at least a portion of said electromagnetic radiation making up said image to produce an electrical representation of said image; sensors configured to provide kinematic data; a control system receiving said kinematic data and estimating jitter-induced motion of said image on said focal plane and outputting a control signal; and piezo-electric actuators configured to receive said control signal and to translate said focal plane along two orthogonal axes and rotate said focal plane about a third orthogonal axis such that jitter-induced motion of said image on said focal plane is reduced, wherein said piezo-electric actuators comprise an X-Y stage comprising a single monolithic piece of metal which has been machined to form flexural joints which are moved by peizo-electric material.
