摘　　要：阐述基于机械式和全固态激光雷达提出一种半固态激光雷达系统,使用MEMS(Micro-ElectroMechanical System)微振镜配合转镜实现三维扫描,完成水平视场角120°,垂直视场角10°的扫描范围,水平视场角分辨率为9.2°,垂直视场角分辨率为0.5°,三维扫描面为三角波。由此,为半固态三维激光雷达提出另一种低成本方案。This paper describes a semi-solid-state LiDAR system based on mechanical and all-solid-state LiDAR,using a MEMS(Micro-Electro-Mechanical System)micro-oscillator with a rotating mirror to achieve three-dimensional scanning,and completing a scanning range of 120°of horizontal field-of-view(HFOV),10°of vertical field-of-view(VFOV),with a horizontal field-of-view(HFOV)resolution of 9.2°,vertical field-of-view(VFOV)The resolution is 0.5°,and the 3D scanning surface is a triangular wave.Another low-cost solution is proposed for the semi-solid-state 3D LIDAR.
