Automatical measurement of mass fraction of transparent solution based on classic optics
Based on classic refraction and dispersion theory,a prism-shaped container was de-signed 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 intelli-gent data measurement and processing were realized by combining the data acquisition card and Lab-VIEW software.Based on classical optical theory,the relation between refractive index and mass frac-tion 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 monito-ring of the mass fraction of single,mixed and flowing transparent solutions.The experimental results were in good agreement with the theoretical results.
