Principles of Operation
The sensor has 64 lasers fixed mounted on upper and lower laser blocks, each housing 32 lasers. Both
laser blocks rotate as a single unit. With this design each of the lasers fires tens of thousands of times per
second, providing exponentially more data points/second and a more data-intensive point cloud than a
rotating mirror design. The sensor delivers a 360
o
horizontal Field of View (HFOV) and a 26.8
o
vertical
FOV.
Additionally, state-of-the-art digital signal processing and waveform analysis are employed to provide high
accuracy, extended distance sensing and intensity data. The sensor is rated to provide usable returns up
to 120 meters. The sensor employs a direct drive motor system with no belts or chains in the drive train.
See the specifications at the end of this manual for more information about sensor operating conditions.
