Abstract

A high-bandwidth driving circuit of FSM (fast-steering mirror) is designed and presented in this paper. The circuit plays an important role in FSM controlling system of the ATP (acquisition, tracking and pointing) system for laser communications. In order to achieve higher bandwidth, smaller size and stability, piezoelectric ceramics and linear power amplifier driving methods are adopted. In the design of the driving circuit, OPA228 and PA93 are selected to constitute bipolar amplification structure to obtain the optimization and balance of magnification and bandwidth. A pre-amplifier is used to achieve a lower input offset voltage and higher bandwidth; a post amplifier to obtain the characteristics of high power and high pressure. In this paper, the working principle and design process of the driving circuit has been described in details and the factors affecting the bandwidth of the circuit are analyzed. Simulations of the driving circuit are validated by using TINA and the experimental results are in agreement with the theoretical analysis.
