Abstract

Based on wavelength modulation spectroscopy and algebraic reconstruction technique, two-dimensional tomography of gas temperature in the range of 400K-1500K and H₂O concentration in the range of 0.05-0.20 was realized. From the numerical simulation, the transmitted signals of two lines using wavelength modulation spectroscopy method are simulated, then the integrated areas of the absorption lines are obtained. Using the integrated areas of two lines, the two-dimensional tomographic reconstruction are derived. It is shown that the reconstructed gas temperature and H₂O concentration are consistent with the predicted value and the most relative errors are 2.21% and 5.17%.
