研究了相干激光通信系统中由反射镜面形畸变造成的信号光波前畸变，进而分析了信号光和相干光波前失配引起的相干效率下降以及误码率的上升。仿真结果表明，反射镜面形的峰谷值对通信链路性能影响较大；相比而言，畸变的大小对于链路性能影响有限。

The single laser wave front aberration caused by reflection mirror in the coherent laser communication is studied. The wave front mismatch caused by the signal to local oscillator field coherence in coherent laser communication systems is analyzed. The simulation result shows that the Peak to Valley(PV) is the main factor which causes the performance decline of laser communication system, while the size of reflection mirror aberration influences the system insignificantly.
