HDL-64E S2 manual_Rev C_2011 - Velodyne Lidar

P R I N CI P L E S O F O P E R AT I O NHDL-32E User’s ManuaIPrinciples of OperationThe HDL-32E creates 360° 3D images by using 32 laser/detector pairs whose housing rapidly spins to scan the surrounding environment.This design allows for the lasers to each fire thousands of times per second, providing a rich, 3D point cloud.Digital signal processing and waveform analysis provide high accuracy, extended distance sensing and intensity data.The HDL-32E uses a direct drive motor system, employing no belts or chains in the drive train, to improve reliability and reducemaintenance. The unit provides:• A 360° horizontal field of view (FOV)• A 41.3° vertical FOV• Usable returns up to 70 metersFigure 1. Overview of the LiDAR HDL-32E 3D Imaging System.[ 2 ]
