摘要
透镜作为一种特殊简单的二元衍射光学元件,推导计算了它带有硬边孔径光阑和高斯激光束入射情况下的光轴上光场复振幅分布的一段表达式,并对几种不同参数的高斯光束情况给出了具体计算结果.当高斯光波退化为平面波和透镜相对孔径较大时,它所描述的光轴上的场分布与《光学原理》.一书上的结果一致.
With the lens as a special simple binary diffractive element, a general expression is derived for describing optical field distribution along axis of the lens with a hard edge aperture and Gaussian incident beam, and for various parameters of Gaussian beam the calculation results are given. While the incident beam degrading to plane wave and the relative aperture of lens being large, the described optical field distribution along the axis of lens 1s consistent with the results given in the book of 'Principles of Optics'.
