| 摘 要： | 用H-S 波前探测器得到校正前后波前相位时间功率谱, 分析了自适应光学控制系统对大气湍流扰动波前的时域校正效果。用这种方法比较了61单元自适应光学系统分别采用P-I 控制算法和Smith 纯滞后补偿控制算法对实际大气湍流扰动波前进行补偿实验时的校正效果。

| Abstract: | Using data which were measured from H S wavefront sensor of an AO system,power spectra density(PSD) was calculated and compared between open loop and close loop conditions.This method can be used to analyze the time domain compensation ability of an AO control system.As an example,the control ability of a 61 element adaptive optics system with PI or Smith control algorithm is compared. |
