Abstract: The closed-loop accuracy of the optical-electric tracking system is one of the important technical index in the fields of reconnaissance and detection, laser communication, etc. Researchers usually use image stabilization techniques, inertial stabilization techniques, or overall self-stabilization techniques to improve the closed-loop accuracy. Inertial stabilization techniques has been widely used in photoelectric tracking system for its good stabilization effect. This paper adopts the method of comparative analysis to analyze the principle, compare the advantages and forecast the development prospect of the frame inertial stabilization, mirror inertial stabilization and inertial reference light stabilization techniques in the photoelectric tracking system. It is proposed that the composite axis inertial stabilization using multiple inertial stabilization techniques is still a development tendency in the near future.
