Novel method for measuring refractive index of liquid

College of Physics &Information Technology,Shaanxi Normal University,Xi-an 710062,China

摘要

摘要: 利用液体薄膜的遮光效应原理，建立了一种新的测量液体折射率的方法和装置。选择了3种常见液体：蒸馏水、无水乙醇和1,2-丙二醇。利用新建的装置对其折射率进行了测量。实际测量过程中，对实验形成的图样进行了2种测量分析：一种是利用读数显微镜直接测量分析实验结果；一种是利用CCD拍摄记录实验结果，并利用计算机对拍摄结果进行了智能化处理分析。分析了实验误差，实现了实时、全自动化测量。测量结果均与理论值吻合。该方法操作简便、设备简单、重复性好、准确度高。

Abstract: A new method for measuring the refractive index of the liquid was proposed and a device was developed by using liquid film shading effect principle. Distilled water, anhydrous alcohol and 1.2-trimethylene glycol were chosen as samples to be measured. The refractive indices of these liquids were measured by the new experiment device. In the measurement process, the experimental graphs were analyzed by two methods. One used the reading microscope to measure and analyze the results directly, the other used the CCD to record and intelligently analyzed the CCD records by computer. Experimental errors were analyzed. Automatic real-time measurement was realized. Measurement results agree with the theoretical calculation. This device is simple, accurate, and easy to operate.
