在波动光学中,光栅衍射是一个重要的内容。在《大学物理》课中,把矩形光栅衍射作为单缝衍射和多缝干涉来进行处理。基于正弦光栅的衍射规律,从傅里叶级数的角度来重新认识矩形光栅的衍射规律,把矩形光栅衍射看成是不同空间频率正弦光栅衍射结果的迭加。这一结果有助于对一般光栅衍射结果的认识和合理地利用光栅衍射进行空间滤波。

In wave optics, grating diffraction is an impoamat content. In ＂College Physics＂ courses, we consider the rectangular grating diffraction as total effects of single slot diffraction and many slots interference. Based on sine grating diffraction result, from Fourier＇ s series view, we restudy the rcctangular grating diffraction and consider the rectangular grating as a series ysis is helpful to understand general grating diffraction and apply grating Key words： Grating, Diffraction, Fourier＇s series, Spatial frequency of sine gratings. This analdiffraction to spatial filter.
