利用楔形薄膜干涉测定液体的折射率

Measurement of Refractive Index of Liquid by Interference of Thin Films

介绍一种利用上下分界面反射率不同的楔形薄膜干涉测量液体折射率的方法 ,并进行了实际测量 ,且分析了产生误差的原因。该方法具有待测量少、简便易行。

A method of measuring refractive index of liquid by interference of wedge shaped thin film,which has two different reflectivity interfaces is presented.Besides,practical measurement is made,and the causes of errors are analyzed.The advantages of this method are fewer measured parameters,simple and convenient,and its precision is better.
