摘要
一般教材在讨论夫琅和费单缝衍射时都没有考虑倾斜因子对光强分布的影响,本文给出了考虑倾斜因子时 的光强分布,并指出当缝的宽度较宽时,倾斜因子的影响可以忽略.
In the discussion about the single gap Fraunhofer diffraction, common textbooks give no consideration of the influence of obliquity factor on luminous intensity distribution. This paper offers luminous intensity distribution influenced by obliquity factor and points out that the influence of obliquity factor can be neglected when the gap is comparatively wide.
