摘要
折射率不仅与几何光学有关,与波动光学也有密切联系,对其的测量方法也多种多样.为了研究不同方法对测量折射率精度的影响,本文利用分光计实验仪器研究了三种不同实验方法测量了三棱镜的折射率,包括掠射法、最小偏向角法和布儒斯特角法,并对三种实验方法测量计算出来的折射率,进行了分析比较.实验结果表明,相对于布儒斯特角法测量三棱镜的折射率,掠射法和最小偏向角法测量的结果更为准确.本文为精确测量三棱镜折射率提供了可参考性的实验方法.
Abstract
Refractive index is not only related to geometric optics,but also closely related to wave optics,and its measurement methods are varied.In order to study the influence of dif-ferent methods on the accuracy of refractive index measurement,the refractive index of a prism is measured by three different experimental methods,including grazing method,mini-mum deviation angle method and Brewster angle method.The refractive index was analyzed and compared.The experimental results show that compared with Brewster angle method,the grazing method and minimum deviation angle method are more accurate in measuring the refractive index.This paper provides an experimental method for accurate measurement of re-fractive index of prism.
