摘要
沙氏大气激光雷达技术是近几年来发展起来的一种新型大气激光雷达技术。该技术以高功率连续波二极管激光器作为光源,图像传感器作为探测器,在满足沙氏成像原理的条件下实现了对大气回波信号的距离分辨探测。介绍了沙氏大气激光雷达技术的基本原理、技术特点、系统结构及大气回波信号处理的一般方法。总结了近年来沙氏大气激光雷达技术在大气气溶胶及大气气体浓度分布探测等方面的研究进展,并分析了当前面临的主要挑战。最后对下一步研究工作及未来发展进行了展望。
The Seheimpflug lidar （SLidar） technique has been recently developed for atmospheric remote sensing. By utilizing high-power continuous-wave laser diodes as laser sources and area image sensors as detectors, the SLidar technique can measure range-resolved atmospheric backscattering signal when the optical layout satisfies the Scheimpflug principle. This paper presents the principle, features, system architecture as well as the signal processing methods of the SLidar technique. The developments and applications of the SI.idar technique in atmospheric aerosol sensing and gas monitoring are summarized in detail. The challenges of the SLidar technique are also discussed. Finally, the future work and the outlook of the SLidar technioue are presented.
