圆环衍射中轴线上的光强分布

The Axial Intensity Distribution of Annular Aperture Diffraction

运用瑞利-索末菲衍射积分、菲涅耳衍射积分、夫琅和费衍射积分分别计算了圆环衍射在孔径轴线上的强度分布,并对计算结果进行了讨论。

In this paper, the axial intensity distributions of Reylaigh-Sommerfeld diffraction, Fresnel diffraction and Fraunhofer diffraction by an annular aperture have been calculated and their results have been discussed.
