摘　　要：采用Zernike多项式拟合元件位相畸变的方法,提出了波前畸变圆孔衍射模型,并进行了波前畸变圆孔衍射及其和理想状态下圆孔衍射的比较.通过分析,不同波长经过球差波前畸变圆孔衍射,最大光强分布的位置是不同的,与理想圆孔衍射的光强分布位置差别比较大,波前畸变对衍射光强分布有很大的影响.Based on the method of Zernike polynomial fitting element phase distortion, the model of circular aper- ture diffraction wave front distortion is proposed in this paper, and circular aperture diffraction wave front distortion and circular aperture diffraction with the ideal state is compared. Though analysis of different wavelengths through the spherical aberration wave front distortion circular aperture diffraction, the position of the maximum light intensi- ty distribution is different, and the ideal circular aperture diffraction intensity distribution is relatively large differ- ences in position, and wave front distortion of the diffraction intensity distribution has great influence.
