系统地研究了非Kolmogorov湍流情况下低阶校正自适应光学系统的性能.从理论上分析了非Kolmogorov湍流情况下相位扰动的空间特性和时间特性,推导了相位扰动的空间结构函数、时间结构函数以及时间功率谱.基于哈特曼—夏克波前传感器,提出了一些测量大气参数的新方法.引入模式时间校正因子和模式非等晕因子,分析了低阶校正自适应光学系统的波前残余误差,并首次对扩展目标情况时低阶校正自适应光学系统的非等晕误差进行了研究.此外还根据实际采集的太阳表面米粒结构图像,采用事后处理的方法研究了倾斜校正自适应光学系统的性能
The performance of low-order correction adaptive optics system under non-Kolmogorov turbulence is studied systematically.The spatial and temporal characteristics of phase disturbance under non-Kolmogorov turbulence are theoretically analyzed and the spatial structure function, phase structure function And time power spectrum.A new method to measure the atmospheric parameters is proposed based on the Hartmann-Shack wavefront sensor.The wavefront residual error of the low-order corrected adaptive optics system is analyzed by introducing the mode time correction factor and the non-equidistant halo factor , And for the first time the non-isosunarial errors of low-order adaptive self-adaptive optics system are investigated when the target is extended.After-treatment method is also used to study the tilt-corrected adaptive optics performance
