In order to analyze aberrations qualitatively, a diffract model of centro-symmetrical optical system has been constituted to simulate the diffract pattern of primary aberrations and second aberrations. Then diffract pattern\'s character of each aberration has been analyzed, and the typical pattern with the value\'s change is given.

为了进行定性分析，文中首先建立了一个共轴旋转对称系统的光学衍射模型，模拟了初级像差和二级像差的衍射图像，并逐个分析了初级像差和二级像差的成像特征，给出了伴随波像差数值变化的典型(来源：8ebeAebBC论文网www.abclunwen.com)图像。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.

According to third-order aberration theory, the conditions of the absence of aberrations were analyzed, and the influences to the remaining high order aberrations of the system caused by the change of the relative aperture of the primary mirror, the position of the corrector and the different combination of the positive and negative lens in the corrector were investigated.
