| 用振幅矢量法计算光栅衍射的光强分布 | |
| 作者单位： | 西南交通大学应用物理系 |
| 摘 要： | 本文介绍一种在普通物理阶段严格计算光栅衍射光强分布的振幅矢量方法，此方法回避了困难的菲涅耳－基尔霍夫积分，这通常在普通物理中是不被采纳的．用振幅矢量法计算有两个显著的优点，一个是物理概念清楚，另一个是计算简单严格 |
| 关 键 词： | 振幅矢量 衍射光栅 光强分布 |
CALCULATION OF THE INTENSITY DISTRIBUTION OF DIFFRACTION FROM A GRATING BY THE AMPLITUDE VECTOR METHOD |
|
| Authors: | Zhang Xinghui |
| Abstract: | For students studying general physics,the amplitude vector method is comprehensible in a rigorous calculation of the intensity distribution of diffraction from a grating.This method avoids difficult calculations with Fresnel Kirchhoff integral that is not usually included in a course as general physics.It has two further advantages:one is its plain physical reasoning,the other is its simple and exact calculation. |
| Keywords: | amplitude vector diffraction grating intensity distribution |
