中文摘要：

在双变形镜自适应光学系统中，需要主激光出射时与信标光的振幅分布一致、相位共轭。当主激光到达目标时，光波的分布与目标上发射的信标光光波分布相同，主激光的振幅和相位都得到了校正。根据双变形镜自适应光学技术的概念，设计了一套基于双变形镜的自适应光学系统，对比了双变形镜和传统单变形镜对波前的空间校正能力，在实验上验证了双变形镜全场校正能力。实验结果表明：通过对光束振幅和相位的全场补偿，能使光束的近场场强得到控制，同时远场焦斑更接近衍射极限分布。传统的单变形镜校正后远场的斯特列尔比为0．71，双变形镜自适应系统校正后远场的斯特列尔比提高至40．85。

英文摘要：

In two-deformable mirrors amplitude distribution and conjugated goal, the beam front of main laser is phase of the main laser have been adaptive optics system, the main phase as the beacon light. When same to that of the beacon light corrected. According to concept transmitting laser has the same the main laser incidences to the in the goal, the amplitude and of the two-deformable mirrors adaptive optics technology, a two-deformable mirrors adaptive optics system was designed. Wavefront corrections of two-deformable mirrors and a single deformable mirror were compared. The feasibility of two-deformable mirrors technology was validated by experiment. Experimental results show that the near-field intensity of laser beam is hold for full field compensation of amplitude and phase, and the focal spot distribution of the far-field is closer to diffraction limit. The Strehl ratio （SR） of far-field image increases from 0.71 to 0.85 using the two DMs AO system instead of conventional AO system.
