分光计最小偏向角法测量方案及其误差产生原因与改进

Error Causes and Improvement on the Method of Measuring Minimum Deflection Angle in Spectrometer

本文介绍了使用分光计测量三棱镜折射率的实验原理,分析了在传统的分光计测量最小偏向角的方法中,还存在着一些不足之处,导致测量结果误差较大,并介绍了一种减小分光计最小偏向角测量误差的改进的实验方法,进而对该方法进行了较详实的分析和介绍。

This paper describes the principle of measuring the refractive index of the triangular prism by spectrometer and analyzes the existing deficiencies in conventional measuring approach,which results in greater measurement error.This paper introduces a new method to reduce measurement error and gives a more detailed analysis and presentation.
