Abstract:

A kind of dynamic tracking system for conducting high accuracy measurement of transparent liquid concentration is designed by means of line matrix CCD receiving fringes in accordance with the relations between liquid concentration and refractive index as well as the relations among refractive index, interference light wavelength of optical fiber F-P interferometer and grade orders. The detecting system can recognize or detect 0.01% of concentration variations via measuring a group of alcohol.
