Abstract:
A system for controlling an optical imaging system capable of providing an image of a target, said system comprising:a closed-loop optical tracking system comprising: a reflector capable of reflecting the image provided by the optical imaging system, wherein said reflector is capable of being adjusted in at least one direction based upon movement of the image received from the optical imaging system; an imaging device capable of recording the image reflected by said reflector; and a tracker controller capable of generating a reflector position drive signal from a position of the target determined based upon the image recorded by said imaging device; and an feed-forward augmentation assembly capable of measuring a displacement of a position of the target, wherein said feed-forward augmentation assembly is also capable of generating a feed-forward augmentation signal based upon the displacement measurement and the reflector position drive signal, and wherein said feed-forward augmentation assembly is capable of combining the feed-forward augmentation signal and the reflector position drive signal to thereby drive the reflector to a position.
