HDL-64E User’s Manual
The HDL-64E operates on a rather simple premise: instead of a single laser firing through a
rotating mirror, 64 lasers are mounted on upper and lower blocks of 32 lasers each and the
entire unit spins. This design allows for 64 separate lasers to each fire thousands of times per
second, providing exponentially more data points per second and a much richer point cloud than
conventional designs. The unit inherently delivers a 360-degree horizontal field of view (FOV) and
a 26.8 degree vertical FOV.
Additionally, state-of-the-art signal processing and waveform analysis are employed to provide
high accuracy, extended distance sensing and intensity data. The HDL-64E is rated to provide
usable returns up to 120 meters.

The HDL-64E employs a direct drive motor system — there are no belts or chains in the
drive train.
