微透镜阵列是夏克哈特曼波前传感器的核心部件。根据液晶空间光调制器(LC-SLM) 的相位调制原理，控制LC-SLM生成焦距、子孔径尺寸和排布方式可调的微透镜阵列，应用于哈特曼波前传感器，对入射光波进行分割，测量子孔径内波面的平均斜率，复原出入射波面的相位分布，以此为校正信号，对畸变波面进行单步校正，校正前后光波的斯特列尔比值从0.12变为0.59。 针对LC-SLM产生的微透镜阵列，讨论了透镜焦距、相邻间距、阵列数目及微透镜性能各影响因素。理论和实验结果表明，基于LC-SLM的动态哈特曼传感器具有子孔径大小、数目和排布方式根据外界条件变化控制灵活，可动态变化的优点。

The micro-lens array is the core component of Shack-Hartmann wavefront sensor. According to the phase modulation principle of liquid crystal spatial light modulator (LC-SLM), the LC-SLM generates dynamic micro-lens array with tunable focal length, aperture size, and arrangement of sub-apertures. Hartmann wavefront sensor based LC-SLM is used to split the incident light. The average slope of each sub-aperture is tested. The phase distribution of wavefront is reconstructed. Then the wavefront aberration is corrected in one step. After aberration, the Strel ratio of the light wave changes from 0.12 to 0.59. For the micro-lens array generated by LC-SLM, heir focal length, adjacent spacing, numbers and performance are discussed in theory and experiment. The results show that the dynamic Hartmann sensor using LC-SLM has the advantages of tunable sub-aperture size, numbers and arrangement according to the external conditions.
