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.
