| 摘 要： | 以惠更斯-菲涅耳原理作为理论基础,探究夫琅禾费圆孔衍射光强分布的一种简便计算方法,在导出其光强分布函数之后,借助计算软件,绘出了光强分布图。最后采用最小二乘法原理拟合出了各级明环和暗环的位置的方程,并利用该方程外推了一些明、暗环的位置,这些外推数据与用光强分布函数直接计算的明、暗环位置能很好的符合。

| Abstract: | Based on Huygens-Fresnel principle,a simple method for calculating light intensity of Fraunhofer diffraction from a circle aperture is presented,and its distribution function is derived explicitly.Then,in virtue of Mathematica software,the distribution graph of light intensity is drawn.Finally,the location equation of fringes is fit by the least square method and is used to extrapolate a few fringe locations.The result shows the extrapolated data are in good agreement with the results calculated by the func... |
