Abstract. To quantitatively analyze the influence of vehicle platform vibration on the vehicle laser radar (LIDAR) measurement accuracy, the modal, harmonic response, and random vibration are analyzed using finite-element software. On this basis, combined with the optical path structure of LIDAR, the deformation of mirror caused by vibration is analyzed. The results show that the maximum deflection of the laser output angle resulting from the mirror deformation is about 0.0001 deg, which is much less than the 0.00573 deg (0.1 mrad) that is required by the performance of the vehicle LIDAR.

振动对车载激光雷达系统的影响分析

摘要。为了定量分析车载平台振动对车载激光雷达（LIDAR）测量精度的影响，使用有限元软件分析了模态、谐波响应和随机振动。在此基础上，结合激光雷达的光路结构，分析了振动引起的反射镜变形。结果表明，镜面变形导致的激光输出角的最大偏转约为0.0001度，远小于车载激光雷达性能所需的0.00573度（0.1毫拉德）。
