摘　　要：基于硬边孔函数能拓展成一组有限复高斯函数的和,研究厄米-高斯光束通过双矩孔的传输特性,用Collins公式分析,用Matlab进行一些数值模拟。表明:传输特性与光束的参数、光学系统的参数、孔的大小和孔的间距密切相关。其结果可推广到其他孔、光束和多光束,本研究对控制光束和光学系统设计是十分有用的。Base on the fact that a hard-edge aperture function can be expanded into a finite sum of complex Gaussian functions, the approximate analytical expressions for the propagation characters of Hermite-Guassian beams passing through double rectangular apertured are derived. The approximate analysis uses Collins formula. At last, Matlab il- lnstrates some numerical examples. It is shows that the propagation characters of Hermite-Guassian beams are closely related to the beam parameters, optical system parameters, the size of apertures and the interval of apertures. The results can be straight forwardly used in other apertures and other beams, also is applied to controlling beams and designing optical systems.
