摘要
以Collins衍射积分公式为基础,利用A0CD矩阵分解与物理实现的技巧,以及将硬边光阑窗口函数展开为有限个复高斯函数之和的方法,推导出了高斯光束通过多级空间滤波器系统的传输方程,并用数值计算加以说明。
Based on the Collins formula, the analytical propagation equations for a Gaussian beam through a multiple spatial filter system are derived by using the methods of the matrix decomposition and expanding the aperture function into a finite sum of complex Gaussian function. In addition, some numerical examples are given.
