FSM Compensation Technology for High Accuracy Airborne Stabilized Sighting System

Abstract

The fast-steering mirror (FSM) is a device used to control the direction of light beam accurately. As a sensitive instrument, it is very significant in astronomical telescope, laser communication, autoadaptation optical system and laser weapon, etc. Aiming at the difficulty of improving stabilization accuracy for airborne stabilization technology, an FSM driven by piezoelectric ceramic is proposed to compensate residual error of traditional integrated stabilized platform in order to improve system stabilization accuracy greatly. Through simulation and experiment validation, it shows that this method can improve stabilization accuracy by more than a magnitude.
