摘要
讨论了平行光斜入射光栅时的衍射现象和光谱特性,得到了平行光斜入射时的光栅方程、主极大级次的变化规律和对光栅的分辨本领和角分辨率的影响,并计算了斜入射角对光栅测波长实验结果的影响,对所得的结论进行了实验验证,其结果和分析结论完全符合。本文的结论对光学测量和光谱分析有一定的实际意义。
With the analysis of diffraction phenomenon and spectrum characteristic precluded parallel beam of light oblique into grating, the following results such as grating equation, primary maximum , resolving pov/er and angular resolution, are made and the influence of oblique incident angle on the grating is measured. By testing the result with exeriment, the conclusion that experimental result coincides with the theoretical analysis is drawn . All the findings are significant in terms of optical measurement and spectrum analysis.
