Abstract
The influence of temperatures and pressures to the intensity of the Brillouin peaks and the Brillouin shift in gas is analyzed by using the Tenti S6 model. The spontaneous Rayleigh-Brillouin scattering (SRBS) spectra in air with different incident wavelength at different altitudes are simulated for the SRBS lidar applications. A system for detecting the SRBS spectra of gas is also introduced in this paper. The SRBS spectra of N2 in different pressures at the incident wavelength of 532nm with the temperature of 300K and the scattering angle of 90° have been measured, the experiment results are well agreed to the simulations.
