Paper Abstract
In order to improve the measurement based on the wavelength modulation spectroscopy technology, a new simulation method of harmonic signals is analyzed and studied. After choosing one H2O absorption line (7185.60cm-1), the transmitted laser signals can be simulated using the measured incident laser signals and fitted laser frequency signals. The simulation of harmonic signals can be realized after creating the lock-in amplifier and calibrated using measured second-harmonic signal. The reliability of this method can be verified according to compare the simulation results with experiment results. At last, the application of this method in the flow field diagnosis is analyzed. It can lay the foundation of engineering application based on wavelength modulation spectroscopy.
