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 analytical formulae are obtained respectively.By using the numerical method,the analytical simulated and the reults can be got from the simulated figure and discuss the numerical calculation result.
