摘　　要：数值模拟了37单元曲率型自适应光学系统的波前校正过程,分析了该系统对低阶Zernike像差的校正效果,结果表明:低阶Zernike像差均能够得到较好的校正。分别对曲率为零和不为零的Zernike像差校正效果进行了对比分析,结果发现:曲率为零的Zernike像差同样可以被曲率型自适应光学系统校正,而且效果好于曲率不为零的Zernike像差校正。The correction of low order Zernike aberrations by a 37-element curvature adaptive optics system is simulated.The results indicate that the system can effectively correct the low order Zernike aberrations.Correction results of Zernike aberrations with zero curvature and with non-zero curvature are analyzed comparatively.It is found that the Zernike aberrations with zero curvature can be corrected,and the correction is more accurate than that for the non-zero curvature aberrations.
