大气探测激光雷达自动准直方法综述

摘要/Abstract

摘要：

大气探测激光雷达工作之前，首先要调整发射激光束与接收望远镜光轴的平行（又称准直或对光），使得接收到正确的回波信号。准直过程一般分为手动和自动两种，手动准直费时费力，有一定的随机和任意性，难以定量评估。因此，高精度、高效率激光雷达自动准直系统的研制是提高激光雷达自动化程度和确保正确探测数据的有效手段。介绍了大气探测激光雷达的工作原理，自动准直方法研究的重要性；综述了大气探测激光雷达自动准直方法，其中着重介绍了激光雷达发射激光的扫描方法和自动准直结果的判定方法，最后比较了不同自动准直方法的优缺点。

Abstract:

The parallel adjustment (also called alignment or boresight) of the transmitting laser and the receiving telescope is essential for an atmospheric lidar system, which could be carried out manually or automatically. Manual alignment is time-resuming and lack of quantitative assessment. A high accurate and efficient self-aligning mechanism is urgently needed for automating the lidar system. Firstly, a brief overview of the fundamental principle of the atmospheric lidar and the importance of self-alignment is given. Next, the self-aligning methodology is reviewed, especially, the scanning method of transmitting laser and the criteria to judge the self-aligning result are introduced. In the end, the merits and drawbacks for different self-aligning methods are summarized.

Key words: lidar, self-alignment, atmosphere detection, backscattering
