摘要
介绍了傅立叶变换理论;用频域分析方法,通过傅立叶变换求解了夫朗和费圆孔衍射的光强分布;将所得结果与文献[1]进行比较发现,二者表面形式不同,但通过空间频率与衍射屏上的坐标之间的坐标变换可得出二者实际一致的结论,且用傅立叶分析法更简单些;求出了几条主要的衍射条纹的相对光强,讨论了它们的位置确定方法,为波动光学中像的处理提供了一条新途径。
The paper refers to the theory of Fourier transformation and its application in calculating the ray's intensity of Fraunhofor diffraction field by circular aperture. The result is different formally but uniform in practicality, and sampler when compared with what is given in the first reference, which offers a new way for dealing with images of wave optics. The relative intensity of a few diffraction stripes and their position are also discussed.
