By means of the Fourier series expansion,an app roximate analytical propagation equation of flattened Gaussian beams(FGBs) passi ng through an apertured paraxial ABCD optical system is derived,and illustr ated with numerical examples,when the transmissivity of the aperture is T( x )=cos( Ωx ).
用傅里叶级数展开法研究了平顶高斯光束通过有光阑限制的近轴ABCD光学系统的传输特性 ,导出了光阑透射率为T(x) =cos(Ωx)时的近似解析传输公式 ,硬边光阑的情况可作为Ω =0的特例得到。
6) light diaphragm
光阑
1.
The cone of optics transmission light loses slightly,moreover it can separate the light to transmission behind light diaphragm to the demand.
