Principles of Operation
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 far more data points per second and a much
richer point cloud than conventional designs. The 64 lasers are employed with each laser/detector pair precisely aligned
at predetermined vertical angles, resulting in a 26.8 degree vertical FOV. By spinning the entire unit at speeds up
to 900RPM (15 Hz), a 360 degree FOV is inherently delivered. Regardless of the spin rate, 1.5 million data
points (i.e. pixels) are generated each second, providing an exponentially richer point cloud than ever before possible.
The HDL-64E supplies returns out to 120 meters. It features ~1 inch distance accuracy and excellent
repeatability. Radial resolution is dictated by spin rate, with radial accuracy as precise as .05 degrees.
Additionally, state-of-the-art signal processing and waveform analysis are employed to provide high accuracy,
extended distance sensing and intensity data.
HDL-64E Output Data Details
The HDL-64E outputs UDP Ethernet packets at 100 Mbps. Interpretation of the data is fully explained in the
user's manual, and each unit comes with a customized calibration file that guarantees ultra-high precision on
both range and angular resolution.
