摘要
为了研究单缝的衍射场,采用波前相因子判断法并考虑到孔径的影响,分析单缝衍射场所含成分及衍射场的积分表达式,导出像面衍射场的振幅分布公式及光强分布公式。并绘出了像面衍射场振幅分布和光强分布图。结果表明该研究为单缝的夫琅禾费衍射场的分析提供了一种新的分析方法。
The content and integral expression of single-slit diffraction fields was studied with wavefront phase factor, while taking the effect of the single-slit aperture into consideration. The amplitude distribution of diffraction fields along image plane and the light strength distribution graph are derived. Accordingly, a new method for analyzing single-slit Fraunhofer diffraction is gotten.
