缺刻光栅:一种特殊不均匀光栅的研究

Study of a special kind of heterogeneous grating:incompletely-inscribed grating

对于光栅的研究,目前大多局限于均匀光栅(即光栅常量d为常量),而对于不均匀光栅却鲜有涉及.为了探究不均匀光栅的光强分布特点,该文选取了一种特殊的不均匀光栅,即缺刻光栅进行研究,得到一般表达式,深入探讨了缺刻条数为1的情况,给出其光强分布具体计算式及主极强,次极强分布情况,并且用计算机模拟出了光栅衍射图样,最后讨论了缺刻光栅可能的应用价值.

Study of heterogeneous grating can commence with the detailed research of the incompletely-inscribed grating, during which the method of vector diagram and a controlled assistance of computer simulation are utilized. Light intensity of different spectrum orders, with s discussion of probable applications of such grating, have been basically presented in the paper.
