Research on laser-based weapons and communication systems is actively being conducted worldwide due to the various advantages of laser characteristics. In these systems, Fast Steering Mirror(FSM) is key components for achieving the required high pointing and tracking performance. Additionally, research is underway to improve performance by applying FSM to surveillance and reconnaissance equipment, such as electro-optical/infrared (EO/IR) systems. As a result, the demand for FSM is steadily increasing, and we research FSM applicable to the various systems mentioned above. In this study, we design an FSM using a Amplified Piezoelectric Actuator(APA) that can compensate for the relatively short displacement of a normal piezoelectric actuator. Before fabricating the prototype FSM, we conducted static and dynamic analyses to ensure that the APA and FSM met the required performance specifications. Subsequently, a prototype FSM was fabricated, and performance tests were conducted to confirm that all necessary requirements were met. In this paper, we present the design process and the performance test results of a prototype FSM.
