| 英文摘要 | Based on laser atmosphere backscattering spectrum, the design and experiment of a raman lidar system for measurement of atmospheric co2 are presented. 354.7nm third harmonic of nd:yag laser is transmitted with 350mj pulse energy and repetition rate of 20hz. the receiver employs a photomultiplier tube with quantum efficiency of 25% and 200mhz photon counter, and it detects raman backscattering 371.66nm(shift 1285cm(-1)) signal. at i h integration, the signal to noise ratio below 2.5km is greater than 8. combinatorial filter is used to reject interference presented by 354.7nm intense mie-rayleigh backscattering and 375.4nm raman backscattering from 0,. we compare the raman return signal at 371.66nm from atmospheric co, with the reference raman return signal at 386.7nm from atmospheric n-2 to retrieve the atmospheric co2 concentration. |
