Patent ID: 7380950

Claim:
A high-bandwidth deformable fast steering mirror system, comprising: an electromechanical fast steering mirror apparatus; a deformable mirror apparatus mounted on said electromechanical fast steering mirror apparatus, said deformable mirror apparatus further comprising: a deformable mirror substrate, a backplane assembly, a plurality of electrostrictive actuators in physical communication with and between said deformable mirror substrate and said backplane assembly, for deforming said deformable mirror substrate, and a plurality of strain gauges, each strain gauge mounted on one of said plurality of electrostrictive actuators, said plurality of strain gauges measuring individual positions of said plurality of electrostrictive actuators and transmitting the positions as actuator position signals; and a closed-loop control system, said control system controlling said electromechanical fast steering mirror apparatus and said deformable mirror apparatus based upon a command input and the actuator position signals.
