摘要
从几何光学理论系统地讨论了棱镜偏向角与顶角的关系,并由Matlab绘出棱镜顶角A与棱镜最小入射角、材料折射率n的关系曲线.结果表明,在测量三棱镜折射率及使用棱镜光谱仪时,对棱镜的顶角是有一定要求的.
In this paper, we discussed the relationship between the deviation angle and the vertex angle of the prism systematically based on the theory of geometric optics. The relation curves of the vertex angle A versus the minimum incidence angle and the refraction index n have been plotted by Matlab software. The result shows that there are some certain requirements for the vertex angle of the prism, when we measure the reflection index or use the spectroscopm instrument.
