缝宽对双光束干涉的影响

The Influence of the Width of the Crack In Two - Beam Interference

在光学课程中,对双光束干涉的讲解,都是假设缝的宽度无限狭窄。本文在考虑缝的实际宽度的情况下,从光场和光强两方面进行深入的研究。

In the optics course, the interpretation about the two - beam interference is always on the ground of the assumption that the width of the crack is boundlessly narrow. Based on the practical width of the crack this article has make profound study in the optic field and intensity of light.
