2) circular aperture diffraction
圆孔衍射

In this paper,on the basis of the scalar diffraction theory of the angular spectrum representation and by taking the circular aperture diffraction as an example,power-series expansion corrections to the paraxial approximation are derived.
当光束具有较大的发散角或光束束腰可与波长相比拟时,傍轴近似不再成立;文章在标量衍射理论角谱表示的基础上,以平面波圆孔衍射为例,给出了衍射场的级数解,分析了级数解的有效性;级数解的适用范围与光束的束腰宽度、传输距离以及所使用的级数解的阶次有关;对受硬边光阑限制的光束,由于高频分量的贡献,当传输距离z较大时,高阶级数解的修正效果不好,甚至失效,级数解的有效范围将受到很大限制。
