摘要
提出一种利用线光源，并通过旋转载物台获得单一的明暗分界线的掠射法测量棱镜折射率的新方案。实验结果表明，该方案容易精确地找到90°掠入射光线的出射线，能大大减小测量误差，提高测量精度。
A new scheme is put forward, in which a linear light source is used for glancing incidence measuring index of refraction of prism, and the only one boundary between light and shade can be exactly found, The experiment results show that the errors are reduced and measuring precision is improved.
