A Rayleigh–Mie-scattering lidar system at an eye-safe 355nm ultraviolet wavelength that is based on a
high-spectral-resolution lidar technique is demonstrated for measuring the vertical temperature profile
of the troposphere. Two Rayleigh signals, which determine the atmospheric temperature, are filtered
with two Fabry–Perot etalon filters. The filters are located on the same side of the wings of the Rayleighscattering
spectrum and are optically constructed with a dual-pass optical layout. This configuration
achieves a high rejection rate for Mie scattering and reasonable transmission for Rayleigh scattering. The
Mie signal is detected with a third Fabry–Perot etalon filter, which is centered at the laser frequency. The
filter parameters were optimized by numerical calculation。
