Abstract The on-line measurement of ozone concentration was carried out by co-correlation and Fourier transform differential absorption spectroscopy. First, a set of generator that can be used for on-line monitoring of ozone concentration in the laboratory was created, and its measurement accuracy can reach 0.1×10-6. Then, the best background spectrum and absorption spectrum can be obtained by calculating the measured multi group background spectrum and absorption spectrum by using the co correlation, so as to accurately retrieve the ozone absorption cross section and optimize the calculation process of ozone concentration. Finally, Fourier transform differential absorption spectroscopy and inverse Fourier transform were used to retrieve ozone concentration in 320～350nm band, the interference of system noise was successfully eliminated and the quadratic equation for retrieving ozone concentration was obtained.
