Measurement of SO2 using Differential Optical Absorption Spectroscopy Based Fourier Transform Filtering

摘要：

　　Differential Optical Absorption Spectroscopy(DOAS) is widely used to determine concentrations of atmospheric species.This paper makes a measurement of SO2 using DOAS based on LabVIEW,and compare the concentrations retrieved by the least squares method and the way of Fourier transform filtering.Experiment results indicate that the Fourier transform filtering is superior to the least squares method for monitoring a single SO2 ingredients.
