2.5 LiAir 220N System Components
2.5.1 Laser Scanner
The Hesai Pandar40P is the LIDAR sensor integrated into the LiAir 220N Ultralight system. The LiDAR
sensor transmits an ultrashort pulse of NIR energy that strikes objects within the Laser Scanner’s field
of view and reflects back to the Laser Scanners receiver as a light echo. By measuring the amount of
time that has elapsed between signal transmission and signal reception (detection), the distance
from the laser scanner to the reflecting object can be determined.
As shown below, the Hesai Pandar40P has a FOV of 360
° horizontally
and 40
° vertically
. Note that
the effective detecting distance of the Hesai Pandar40P varies based on where the object is within
the FOV. The closer to the edge of the FOV, the shorter the effective detecting distance is. The closer
to the center of the FOV, the further the effective detecting distance.
