摘要
采用矩阵分解的方法,从柯林斯衍射积分公式出发,对高斯光束通过失调空间滤波器的传输特性进行了分析,得到了相应的解析式。通过对解析式的模拟,得出了直观的结果,并对模拟结果进行了分析。
Based on the method of matrix decomposition, and the Collins diffraction integral formulae, the propagation characteristics of a Gaussian beams passing through misaligned spatial filter are studied. As a result, corresponding an- alytical formulae are obtained respectively. By using the numerical method, the analytical simulated and the reuhs can be got from the simulated figure and discuss the numerical calculation result.
