英文摘要Laser heterodyne spectroscopy has been widely used in greenhouse gas detection and laser atmospheric transmission in recent years, because of its high spectral resolution, simple structure and low cost. A laser heterodyne spectrum detection system using 3. 66 mu m DFB laser as local oscillator source was designed. The real-time and accurate measurements of water vapor absorption spectrum in the whole atmosphere was also realized. Furthermore, the signal-to-noise ratio after 12 averaging is 160. 4, and the spectral resolution is 0. 009 cm(-1). The average values of water vapor column concentration of Hefei on May 22 and 23 are 1549 ppmv and 1730 ppmv respectively. By comparing and analyzing the measurement results of laser heterodyne spectrometer and Fourier transform spectrometer (EM27/SUN), the correlation between them is 0. 895 and 0. 819, and the deviation is 14. 2% and 11. 2% respectively. With the design and research of the system, the real-time measurements of the solar absorption spectrum of water vapor in the atmosphere and the precise inversions of water vapor column density were realized, which laid a foundation for more accurate detection and concentration inversion of the absorption spectrum of water vapor and its isotope HDO.
