摘要
应用光栅方程测量光栅常数或光波波长,若入射光偏离垂直光栅平面方向将导致测量结果出现误差,本文分析了在入射平面内倾斜入射的角度与实验误差的关系。
When the grating equation is used to calculate the grating constant or the wavelength in the grating diffraction experiment, the deviation will be induced if the.incident light is not vertical to the grating plane. In this paper, the relationship between the deviation and incident angle was anayzed.
