Paper Abstract

Based on the analysis of principle of tracking and aiming system, some important factors to design the structure of tracking-aiming system and the layout of optical system are discussed. Besides, the paper gives the present developing situation of fast-steering mirror at home and abroad, analyzes the advantages and disadvantages of FSM with axis, and presents a novel design of flexible axis FSM. The main axis of composite axis system is tracked by motor to drive the frame, and the sub-axis is tracked by voice coil motor (VCM) to drive FSM. The structure of FSM and designing principle of VCM are introduced, and the emulation analyses of inherent frequency and deformation under load of the FSM with software COSMOS are also given.
