Abstract

An optical deflector designed to stabilize the position of the image at the input aperture of the optical system has been developed. The deflector contains an electronic control unit that operates with digital and analog input signals and an actuator based on piezoceramic actuators and a flat mirror. Special design solutions of the actuator ensure that the flatness of the mirror remains in the entire range of correction angles, and the electronic damping system suppresses the vibration of the mirror under a pulsed control signal. Adaptive optics systems with the described deflector are applicable in astronomical telescopes, in ground-based video surveillance and laser scanning systems.
