Paper Abstract

Improving the bandwidth of fast steering mirror is the important premise when adaptive optics is applied to space communication. In this paper, based on the fast steering mirror structure, the resonance frequency and its vibration model of the mirror, driving elements and bend-board of fast steering mirror (FSM) are analyzed in detail by use of finite element analysis. It is concluded that the unreasonable structure of the bend-board which fixes and supports the fast steering mirror is the main reason why the fast steering mirror has lower resonance and the resonance frequency of the bend-board has the great influence of the parts of the whole fast steering mirror. In addition, the optimized design to improve the resonance frequency of the FSM mounting is put forward.
