Abstract

Miniaturization and low-cost laser communication terminal is the development direction of space payload. MEMS fast steering mirrors (FSM) has the characteristics of small size, low power consumption, large deflection angle, high closed-loop control bandwidth and low cost. It is a potential fast steering mirror to realize the miniaturized laser communication terminal beam high-precision scanning and pointing, and is also one of the development directions of low SWaP-C laser communication terminal technology. For space laser communication terminal pointing acquisition and tracking (PAT) system, the optical and mechanical characteristics of MEMS fast steering mirror used in beam deflection mechanism are analyzed in combination with theory and engineering application. According to the quasi-static working mode of MEMS fast steering mirror for fine pointing assembly (FPA) and point ahead angle (PAA) mechanism and the resonant working mode for nutation coherent tracking mechanism, the static and dynamic plane types, working bandwidth and scanning angle, closed-loop control accuracy, volume, weight, power consumption and reliability requirements of MEMS fast steering mirror are analyzed in detail. The technical parameters of MEMS FSM for space laser communication are presented, which can provide reference for its application in space laser communication system.
