摘要
应用付里叶变换讨论了以网格（二维正交粗光栅）为衍射屏的双（线）光源衍射理论，并介绍了用网格衍射测量光波波长或网格常数的实验方法。
In this paper , Fouries transformation is used to discuss the theory of auze diffraction of light waveemitted from two lines light source, and an experimental method of determining the light wavelength orauze constant by auze diffraction is introdued.
