本文建立了基于电荷耦合器件(CCD)的大气侧向散射系数廓线反演装置。利用该装置,测量了33°到145°散射角范围内的大气侧向散射光强;通过将CCD收集的空间散射光投射到平面散射角上,实现了CCD像元与散射角的对应,最终实现大气侧向散射系数廓线反演。装置采用的连续激光器还很好地解决了反演大气侧向散射系数廓线的实时性问题。

A device which can illustrate the side-scattering coefficient profile of atmosphere was established in this paper.Based on charge coupled device(CCD),the device inversed the coefficient profile by measuring the side-scattering intensity with the scattering angle ranges from 33° to 145°.By projecting the collected side-scattering light to a plane,we realized the correspondence between the CCD pixels and scattering angle,and inversed the side-scattering coefficient profile at last.The device also upgraded the real-time performance by adopting CW green laser source and CCD with high frame rate.
