Velodyne Acoustics LIDAR HDL-32E - Manual (Page 5)

Principles of Operation
The 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 reduce maintenance.
The unit provides:
• A 360° horizontal field of view (FOV)
• A 41.3° vertical FOV
• Usable returns up to 100 meters
