| 摘 要： | 利用几何光学原理和计算机进行模拟，对棱镜出射光线与入射点的关系进行了研究，并由MATLAB得到了入射点与棱镜顶角、材料折射率及棱镜底面边长关系的曲线图。实验结果表明，在测量三棱镜折射率及使用棱镜光谱仪时，对入射光线的入射点是有一定要求的。 |
| 关 键 词： | 入射点 折射率 棱镜 顶角 |

| Abstract: | In this paper, the relationship between the emergent light ray angle and incidence point is investigated according to the principle of the geometric optics and the computer simulation experiment so as to obtain the dependence of the incidence point on the vertex angle of the prism, refraction index and the basal-plane length of the prism from MATLAB. The experimental result shows that a certain incident point of the incident light is required for the measurement of reflection index of a prism and the application of a spectroscopic instrument. |
| Keywords: | incident point reflection index prism vertex angle |
