激光通信中主要存在的问题为激光在传输过程中受大气环境影响严重，产生波面畸变，影响激光的传输质量，从而引起激光所携带的信息失真。以哈特曼传感器为核心研制一个操作简便、结构紧凑的波面测试系统，该系统可有效地检测激光传输后及传输过程中产生的波像差。通过对所要求的技术指标进行分析，合理地选择了满足要求的哈特曼波面传感器及微透镜阵列，根据微透镜阵列的口径对准直光学系统进行了设计，编制了测试软件界面，给出了波面测试实验结果，最终满足测试指标要求。

In recent years, the domestic industry of laser communications had developed rapidly. However, the laser transfer process is severely affected by the atmosphere in the laser communication;the transmission quality of the laser would be affected and the information carried by laser would be distorted by the wavefront distortion which is produced by atmosphere attenuation. In this paper, a simply operating and compact wavefront test system was proposed. The wavefront aberration produced in the process and after laser transmission could be effectively detected. Through the anal-ysis of the required technical specifications, a reasonable choice of the Hartmann-Shack sensor and micro lens array were given. The collimating optical system had been designed according to the micro lens array aperture. The test soft-ware had also been developed;the wavefront test results were given and the testing requirements were met.
