| 摘 要： | 本文在用耦合波理论研究平面光栅的基础上,提出了分析和解决凸球面光栅衍射效率问题的方法,并从中得出一些有意义的结论：在凸球面光栅的口径半径比较小时,求解其衍射效率可以转化为平面光栅问题来处理。

| Abstract: | In this paper,the method of the diffraction efficiency of convex rectangular grating is proposed by using the coupled-wave theory,and some useful conclusions are gotten： we can calculate the efficiency of convex grating by taking it as a plane grating problem,when the caliber-radius ratio is little. |
