摘要
本文导出了直角刻槽反射光栅在正入射和非正入射以及刻槽偏离直角等情况下,反射夫朗和费(Fraunhofer)衍射强度分布表达式;用数值计算结果,分析和讨论了这种光栅的后向衍射特性.
In this paper, the Intensity function of reflected Fraunhofer diffraction by reflecting grating with right angle grooves has been derived in the cases of the normal incidence and unnormal incidence of rays and the ruled grooves deviated from right angles. The retrodiffraotion properties of the grating are also analysed and discussed according to the numerical results.
