Abstract
(EN)
A laser radar system apparatus for the multi-wavelength measurement of the atmospheric carbon dioxide concentration and a vertical aerosol profile, comprising: a laser transmitting unit; a dual-pulse laser (4) capable of simultaneously transmitting laser having three wavelengths, i.e., 1572 nm, 1064 nm, and 532 nm; a transmitting beam expander (5); a receiving telescope system (6); a visual axis monitoring module (7); a photoelectric detection unit (9); and a data acquisition and processing unit (15). The laser (4) that simultaneously outputs laser having three wavelengths is used in a laser radar system, and an optical differential absorption method and a high spectral resolution detection method are used, such that the atmospheric carbon dioxide concentration and the vertical aerosol profile can be measured simultaneously and high-precision aerosol monitoring is implemented during the high-precision obtaining of the concentration of the greenhouse gas carbon dioxide.
