丝袜衍射图样探究

奇妙的丝袜衍射图样,引起深入思考。通过多圆孔衍射与光栅衍射的类比,结合单圆孔的衍射和光栅的多缝间的干涉,得出二维多圆孔夫琅和费衍射的光强公式。采用MATLAB编程作图,得到二维夫琅和费多圆孔衍射的图样。提出了一种制作多圆孔衍射器件的途径,有助于大学物理教学。

The wonderful diffraction pattern of silk stockings causes deep thinking.By comparing the diffraction of multiple circular holes with grating diffraction,and combining the diffraction of a single circular hole with the interference between multiple gaps of grating,the light intensity formula of fraunhofer diffraction of two-dimensional multiple circular holes is obtained.Using MATLAB programming drawing,the two-dimensional multi-circular hole fraunhofer diffraction pattern is obtained.In this paper,a method for fabricating multihole diffraction devices is presented,which is helpful to physics teaching in university.
