夫琅和费正交双缝衍射干涉光强分布的讨论

The Fraunhofer Diffraction Illuminance Distribtion of Cross Double Slit

用傅里叶变换的方法，计算夫琅和费正交双缝的衍射光强分布，作了详尽的讨论，求出了光强分布中所包含的全部空间频率、空间周期和干涉条纹的走向。以列表方式归纳在一起。

This paper calculates the Fraunhofer diffraction illuminance distribtion of cross double slit by Fourier transformation,offers a detailed discussion of it,and has obtained all its spatial frequency,its spatial period and the direction of its interference fringe.The paper sums up all the above on a list and a correct conclusion has been obtained.
