用半波带法求单缝衍射的光强分布

SOLVING INTENSITY DISTRIBUTION OF DIFFRACTION BY A SINGLE SLIT BY THE METHOD OF FRESNEL ZONE

半波带法是研究衍射问题的一种简便而直观的方法。本文给出了用半波带数表示的单缝夫琅和费衍射光强公式,并据此对光强分布特点作了更为直观的讨论。

In this paper, the author gives a formula for intensity of Fraunhofer diffraction by a single slit, It is the formula represented by number of Fresnel zone. By the formula, intensity distribution can be discussed more directly.
