A corrector mirror assembly within an optical train provides corrections to maximize energy concentration on a distant target, despite phase perturbations due to air medium turbulence. Phase correction is by mirror surface deformation provided by piezoelectric actuators and a companion, unique, solid-state, electronic amplifier. Desired actuation bandpass requirements are 1 kHz. This paper describes the overall actuation control with emphasis on the actuator and drive amplifier analysis, design, and simulation. Hardware examples are briefly presented.
