| 摘 要： | 在标量衍射理论的基础上，给出了圆屏（球）和圆环菲涅耳衍射的振幅及光强解极表达式。计算了光强分布曲线，并将计算实例和有关资料中的实验与计算结果进行了比较。同时指出所谓无衍射光束实际上是一种菲涅耳衍射现象。

| Abstract: | The amplitude and intensity analytic expressions for disk (sphere) and annular aperture Fresnel diffraction are given on the base of scalar diffraction theory. The intensity distribution curves are compared with the other examples and results in the references. It is pointed out that the non diffracted beam is a kind of Fresnel diffraction phenomenon. |
