基于光纤M-Z干涉原理的透明液体浓度测量系统
Transparent Liquid Concentration Measurement System Based on Fiber Optic M-Z Interference Principle
摘要
Abstract
For general liquids,the refractive index is generally different for different concentrations,and there exists a certain linear relationship between the two.Based on this principle,a device sensitive to the refractive index of the solution can be used to measure the concentration.This thesis proposes a test system based on the optical fiber MZ interference principle,through the liquid concentration to change the optical range difference in the optical fiber,at different light wavelengths to produce interference valleys,compare the wavelength change of the interference valleys in distilled water and solution,you can calculate the concentration of transparent liquid.Concentration tests were carried out on the propanetriol solution with an effective test range of 0-50%,a measurement accuracy of 0.762%,a linear fit up to R2=0.988,and an uncertainty of±0.587%.关键词
