摘要 激光雷达多用于精确测量障碍物的位置信息(距离和角度)、运动状态和外观形状,进行探测识别、分辨和跟踪,完成三维地图绘制等,是无人驾驶必不可缺的核心器件。本文考虑了车载激光雷达的实际使用环境和应用需求,在计算分析光学系统参数的基础上,利用ZEMAX光学设计软件的非序列模式,采用三片球面透镜激光准直结构为初始结构,利用欧司朗SPL PL90-3半导体激光发射元为激光光源设计了一款工作在905nm波段,焦距为70mm的32线激光雷达发射光学系统。设计结果表明,该激光发射系统对人眼安全,探测距离大于100 m,角度分辨率为0.26°,完全能满足无人驾驶汽车的要求。 LIDAR can achieve many functions, such as accurate measurement of laser target position (distance and angle), motion and shape, detection, recognition, distinguish, tracking, and three dimensions mapping, so LIDAR is a key component of automotive vehicles. In this paper,the actual application environment and application requirements of LIDAR for vehicles were considered. On the basis of calculating and analyzing the parameters of optical system, an emission optical system was designed by the non-sequential mode of ZEMAX software. This 32 lines LIDAR has an initial structure of three lens laser collimation system, which uses OSRAM SPL PLg0-3 semiconductor laser element as the laser light source. The wavelength of the system is 905 nm and the focal length of the system is 70 mm. The design results show that the laser emission system is safe for human eyes. The detection distance is more than one hundred meters and the angle resolution is 0.26 degree, which can fully meet the requirements of automatic vehicles.
