Abstract
The research on the detection of sulfur dioxide volume fraction in flue-gas is a hot topic all the time.Based on the analysis of the measuring principles for the sulfur dioxide volume fraction using ultraviolet fluorescence method
a new measuring method using time-divided double optical paths is proposed.This method overcomes the problems of cross sensitivity and background noise in single path measurement because it takes advantage of the fluorescence signals produced by the alternation of two light filters.
