Abstract
A laser radar system apparatus for the multi-wavelength measurement of the atmospheric carbon dioxide concentration and a vertical aerosol profile, including: a laser transmitting unit; a dual-pulse laser capable of simultaneously transmitting laser having three wavelengths, i.e., 1572 nm, 1064 nm, and 532 nm; a transmitting beam expander; a receiving telescope system; a visual axis monitoring module; a photoelectric detection unit; and a data acquisition and processing unit. The laser 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.
