Wavelength modulation spectroscopy has not yet formed an efficient method applied to measure line shape, which has restricted the development of tunable diode laser absorption spectroscopy. In the present paper, we have established a method which can recover line shape directly by using the data of the X and Y axes of odd harmonics based on the absorption spectral and harmonic theories. And then, in validating the accuracy of this method, the numerical simulation was used to recover the line shape of the transition at 6527.641cm-1. Meanwhile, the experimental results show that the method established in this paper can recover the line shape accurately.
