透射光栅衍射率的实验标定和数值计算

Experimental Calibration and Calculation of Diffraction Efficiency for Transmission Grating

简要介绍了实验室中使用的三种透射光栅的结构。在北京同步辐射源上实验标定了这些光栅的相对衍射效率。借助于光栅模型，得到了光栅的重要结构参数。

Configurations of the three transmission gratings used in our laboratary are introduced briefly. Relative diffraction efficiencies for these gratings have been calibrated on synchrotron radiation source. With the help of grating model, the important structure parameters of grating are obtained, and absolute diffraction efficiencies for these gratings are calculated and discussed.
