摘要
激光雷达可以高精度、高准确度地获取目标的距离、速度等信息或者实现目标成像,在测绘、导航等领域具有重要作用。本文首先介绍了从机械式向全固态过渡的微机械系统激光雷达解决方案;其次针对激光雷达全固态的发展需求,介绍了面阵闪光、相控阵激光雷达的基本原理和典型实现方法,从液晶、光波导材料等研究方向阐述相控阵激光雷达研究现状;最后总结了目前激光雷达存在的问题及不同的解决方案,并对未来发展趋势进行了展望。
Abstract
Light detection and ranging (LiDAR) system can be used to capture the distances and speeds of the tar-gets with high resolution and high accuracy, and can also form imaging. It is important for the applications such as mapping, and navigation, et al. This paper introduces the LiDAR solution based on micro-electromechanical system (MEMS) is a transitional scheme from mechanical one to solid-state. Meanwhile, in terms of the requirement of sol-id-state, the principles of Flash and optical phased array LiDAR are introduced in this paper. At the same time, the miniaturization trend of LiDAR is presented with optical phased array based on liquid crystal (LC) and integrated optical waveguides. At last, the performances and open issues of the solutions for LiDAR are concluded and the development trends of LiDAR are summarized with outlook.
