Based on the method that a rectangular function can be expanded into a sum of complex Gaussian functions with finite numbers, the propagation characteristics of a Gaussian beam passing through apertured spatial filter systems are analysed and the corresponding analytical formulae are obtained respectively.

根据矩形函数可以展开为有限复高斯函数之和的方法，从柯林斯衍射积分公式出发，对高斯光束通过受限空间滤波器传输特性进行分析，得到了相应的近似解析式。

It is shown that focal shifts of apertured FGBs not only depend on the beam order N, Fresnel number F w associated with the beam, but also depend on the Fresnel number F a associated with the aperture.

研究表明，截断平顶高斯光束的焦移不但由光束的阶数N、光束菲涅耳Fw决定，还与孔径菲涅耳数Fa有关。

Based on the generalized Huygens Fresnel diffraction integral, the propagation of the Bessel modulated Gaussian beams with quadratic radial dependence ( QBG beams) through a circle apertured ABCD optical system has been studied.

基于惠更斯菲涅尔广义衍射积分，对变量为径向平方的贝塞耳函数调制的高斯光束（QBG光束）通过有圆孔光阑限制的一阶ABCD光学系统的传输进行了研究。
