自适应光学系统能够实时测量并补偿光波受动态干扰所造成的波前畸变,使光学成像系统得到接近衍射极限的目标像。在分析大气湍流对空间目标成像的影响及其统计参数的基础上,介绍了自适应光学的组成、工作原理、工作流程及其特点,阐述了自适应光学在激光、航天和通信等军事领域的广泛应用。
Adaptive Optics(AO) can reconstruct object images that are near the diffraction limit through real time measuring and compensating the wave-front aberrations which are affected by dynamic disturbance.Based on the studies of the effect to space object imaging and statistic parameters of atmospheric turbulence,the paper presents the structure,principle,flow and characteristics of AO.Then the extensive applications of AO in laser,spaceflight,communication and medical treatment are introduced.
