摘要:

在光学实验中,使用涨落有序的相干光或激光束通过单缝衍射实验仪有衍射条纹伴生。于是近代《光学》理论认为光是一种波或电磁波,所以它绕过障碍物而发生了衍射。但作者经长期大量工作后认为衍射条纹的产生是大量光(粒)子跟单缝之缝壁作用下的统计结果。本文从这观点出发,运用惠更斯包络面概念、以及点光源辐射产生球形包络面——球面波,结合图象做了数学运算,得到跟传统波动光学相同的结果。

In the optical experiment, the diffraction pattern of coherent light or laser beam with a single slit diffraction experiment is used. So the modern optical theory suggests that light is a wave or elec-tromagnetic wave, so it passes around obstacles and diffracted. However, after a long period of work, the author thinks that the diffraction fringes are the result of a large amount of light (granule) slits. From this point of view, this paper using huygens envelope concept, and the point source radiation produce spherical enveloping surface, spherical wave, combined with image to do the math, get the same results with traditional wave optics.
