摘　　要：光栅和光栅衍射是波动光学中的一个重要内容，讨论利用多个圆环衍射的圆环型达曼光栅的衍射现象．首先设计了一种三圆环型达曼光栅，然后解析推导了圆环型达曼光栅的光强分布规律，并数值分析了其中出现的缺级现象，从而使学生对光栅及光栅衍射有一个更深入的了解．The ring diffraction in important phenomenon in the design of optical devices. This paper discusses the ring- shaped Dammann grating, which is an optical device using a number of circular diffraction. In this paper, a three-ring- shaped Dammann grating is designed and the distribution of light intensity for the ring - shaped Dammann grating is analyzed. Therefore a specific missing order of Dammann grating is investigated.
