| 摘 要： | 建立了采用直接斜率波前控制算法的自适应光学系统中各阶泽尼克模式间的动态关系，通过对比系统对大气湍流畸变波前各阶泽尼克模式的功率谱抑制函数，揭示了采用直接斜率波前控制算法的自适应光学系统中各阶模式校正效果间的差异，并初步分析了造成这种差异的原因。用在61单元自适应光学系统上取得的实验结果验证了理论分析结果。

| Abstract: | The dynamic relationship of Zernike modes in an adaptive optics (AO) system using direct\|gradient wavefront control algorithm was established. By comparing the power spectra rejection function of those Zernike modes that describe the atmosphere disturbed wavefront, the phenomena of different compensation effect for those Zernike modes in an adaptive optics system using irect\|gradient wavefront control algorithm were indicated and the reason of causing different compensation effect was analyzed. The theoretical results were verified using the experimental results on a 61\|element adaptive optics system. |
