摘要
介绍了一种利用干涉原理测定液体折射率的新方法。其基本特点是不需要取样 ,直接无干扰地测定平行平板液池内介质的折射率 ,在适当控制实验条件的情况下 ,测量精度可以达到小数点后 5位。对如何简化计算并消除池壁参数的影响以提高测量精度等问题进行讨论 ,给出了分析结果。以水为检测对象 。
A novel method using interferometry to measure the refractive index of liquid is presented Its main feature is: without the need of sampling, directly, non intrusively measuring the refractive index of liquid in the parellel plate cell, under a certain conditions an accuracy to the fifth decimal place can be achieved How to reduce the calculation, eliminate the effect of the cell parameters on the accuracy are discussed and the analytical result is given Experimental verification for liquid water has been carried out
