摘要
基于经典的折射和色散理论,设计了可使光路发生平移的棱柱形容器,并以此为基础搭建了自动化实时测量质量分数的装置.采用位移传感器替代传统的观察屏提高了光点位移测量的精确度,结合数据采集卡与LabVIEW软件实现了数据测量和处理的动态化、自动化和智能化.基于经典光学理论建立折射率-质量分数关系,实现多种透明溶液质量分数及混合溶液中各组分质量分数的实时测量.该装置可实现单一、混合以及流动透明溶液质量分数的实时自动化监测,实验结果均与理论符合良好.
Based on classic refraction and dispersion theory,a prism-shaped container was designed to shift the light path.Furthermore,an automated real-time mass fraction measurement setup was developed.The displacement sensor was adopted to improve the accuracy of spot displacement measurement instead of using the traditional observation screen.The dynamic,automatic and intelligent data measurement and processing were realized by combining the data acquisition card and LabVIEW software.Based on classical optical theory,the relation between refractive index and mass fraction was established,and the mass fraction of various transparent solutions and each component in mixed solutions could be measured in real-time.The device could realize real-time automatic monitoring of the mass fraction of single,mixed and flowing transparent solutions.The experimental results were in good agreement with the theoretical results.
