【摘要】 为了探测大气气溶胶1064 nm波长后向散射系数垂直廓线和大气水平能见度,研制了一台车载式1064 nm米氏散射激光雷达系统(MMSL)。介绍了该激光雷达系统的结构和技术指标,叙述了光学机械结构的设计与装校,解决了激光雷达系统结构的稳定性、激光发射光束与接收光学单元光轴的平行以及运输过程中的防振等问题。简要叙述了相关的数据处理方法,给出了该激光雷达与美国Belfort 6230A能见度仪探测大气能见度的对比结果,两者具有较好的一致性。与较早前研制成功并已应用于常规观测的一台532 nm米氏散射激光雷达进行了大气后向散射系数的对比验证实验,两者的探测结果具有很好的相关性。结果表明,该激光雷达具有较高可靠性和准确性。更多还原

【Abstract】 A mobile 1064 nm Mie scattering lidar system has been developed which can measure the vertical aerosols backscatter coefficient and horizontal visibility.The configuration and specifications of the Mie scattering lidar system are presented and the designed alignment of the optical mechanic unit is described.As a mobile system,the transportation stability of the lidar system is solved and the optical transmitting and receiving axis are well aligned.Validation experiments are made in Hefei.The vertical backscatter measurement is compared with another 532 nm Mie scattering lidar and the visibility measurement is compared with Belfort 6230A visibility sensor.Both results are in good agreement which indicates the new made mobile 1064 nm Mie scattering lidar is stable and reliable.更多还原
