摘要
用离焦打靶和楔角偏差等方法能方便有效地改善正交光楔列阵系统（ＳＷＡ）的大尺度幅照均匀性．基于标量衍射积分方法和旁轴矩阵光学方法，对以上两种方法进行了详细的分析，给出焦斑光强分布特性的理论计算、实验结果和系统最优设计参数．
Using the target off focus plane,the illumination uniformnity of large scale for the cross segmented wedge array can be improved by suppressing the diffraction of SWA.In this paper,based on adaxial matrix optics and diffraction integral detailed theoretical for the two means is analyzed and the intensity distribution on the target by numerical calcuilation and experimental results and optimum design of the system parameter have been given.
