TEA-CO2差分吸收激光雷达回光探测
Atmosphere Backscattering Experiment of TEA-CO2 Difference Absorption Lidar
摘要
介绍了TEA-CO2差分吸收激光雷达(DIAL)在大气回光探测中所采用的相干探测外差接收的探测原理,详细介绍了光路的实现。利用该探测原理进行了大气回光探测,探测距离达15 km以上,探测高度达7 km,与采用短波差分吸收激光雷达进行直接探测（探测距离为3～4 km）相比探测能力有了明显的提高。
Abstract
The theory of optical heterodyne of coherent detection is introduced, which is used in TEA-CO2 differential absorption lidar (DIAL) technique to detect backscattering light of atmosphere. And the correlative optical setup is emphasised. The atmosphere backscattering experiment is carvied out based on the theory. The result shows that the distance of detection of the lidar reaches over 15 km with 7 km altitude of detection. Compared with short-wavelength lidar (detection range is 3～4 km), the long-wavelength lidar has more powerful detection capability.
