By using the direct wavefront gradient control method, numerical simulation of all parts of an adaptive optics (AO) system is carried out. We present “phase cutting” of the calculated phase to solve the problem that variance of the calculated residual wavefront is not corresponding to the correction effect of AO system. The computational results in imaging of lenses by means of the fast Fourier transform (FFT) method agree excellently with those by means of integration method. It is found...

By using the direct wavefront gradient control method, numerical simulation of all parts of an adaptive optics (AO) system is carried out. We present “phase cutting” of the calculated phase to solve the problem that variance of the calculated residual wavefront is not corresponding to the correction effect of AO system. The computational results in imaging of lenses by means of the fast Fourier transform (FFT) method agree excellently with those by means of integration method. It is found for the first time that for a constant delay time of an AO system, the compensation effect of the AO system is better than that of complete phase compensation when the velocity of lateral wind exceeds a threshold. It is shown that a better compensation capability of an AO system does not mean a better correction effect.

采用直接斜率控制法完整地实现了对自适应光学(AO)系统的数值模拟,系统研究了带自适应光学校正的激光大气传输规律。提出了对计算出的位相进行“剪接”的办法,解决了残余位相方差与自适应光学的校正效果没有对应关系的问题。证明可以把快速傅里叶变换法(FFT)用于透镜成像的聚焦计算,与积分法得到相同的结果。报道了对于一定的延迟时间,当大气横向风速大于一个阈值时,自适应光学补偿比完全相位补偿的效果还要好,表明在一定的条件下自适应光学系统的校正能力并非越大越好

The relationship between the effective bandwidth and the close bandwidth in adaptive optics (AO) control systems is discussed. The bandwidth of an adaptive optics control system is cpmpared with PI controller or pure time delay compensative controller too. The conclusion is that the time delay in AO system is the limitation of Bandwidth, and an AO control system should have higher Effective Bandwidth and lower Close Bandwidth.

分析了自适应光学控制系统中闭环带宽与对湍流校正的有效带宽的关系,比较了采用比例积分控制和纯滞后补偿控制的自适应光学控制系统的带宽。分析结果认为自适应光学控制系统应当具有较高的有效带宽,较低的闭环带宽,系统中的时间延迟是限制自适应光学控制系统有效带宽的主要因素。
