HDL-32E User’s Manual

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
