Abstract

A novel on-line measuring method with four-terminal optical compensation network has been presented in this paper. It can eliminate influences of the fluctuation of light source, the transmission loss of light in optical fibers, the variation of amplifiers' gains and the characteristic value drift of photo-detector, so the signal-noise ratio of sensor is increased clearly. The concentration measurement system using this detective method can make the detective value of the concentration reliable and accurate when it is used in the on-line measurement.
