%X 激光雷达技术已广泛应用于无人驾驶、船只航行、远距离探测等领域&#65292;展现出卓越性能。然而&#65292;现有商用激光雷达高度集成化&#65292;难以在教学中直观展示其内部结构和工作原理。为此&#65292;开发一套结构简洁、易于讲解的激光雷达选通成像演示系统具有重要意义。在搭建过程中&#65292;面临反射光收集困难、激光散射严重、测距及选通成像实现复杂等问题。本文提出通过暗室环境减少散射、外接测距芯片提升测距精度、时间选通技术实现成像等解决方案&#65292;并对未来改进方向及现存问题的解决思路进行了探讨&#65292;旨在为激光雷达教学与研究提供有效支持。<br>Lidar technology has been widely applied in fields such as unmanned driving, ship navigation, and long-distance detection, demonstrating excellent performance. However, the existing commercial LiDAR is highly integrated, making it difficult to visually demonstrate its internal structure and working principle in teaching. Therefore, it is of great significance to develop a laser radar gating imaging demonstration system that is structurally simple and easy to explain. During the construction process, there are difficulties in collecting reflected light, severe laser scattering, and complex implementation of ranging and gating imaging. This article proposes solutions to reduce scattering in a dark room environment, improve ranging accuracy through external ranging chips, and achieve imaging through time gating technology. It also explores future improvement directions and solutions to existing problems, aiming to provide effective support for laser radar teaching and research.
