FOV Coverage
The gure below shows the FOV coverage of the L1 compared with non-L1 LiDAR sensors that use
traditional mechanical scanning methods.
A. When the integration time is less than
0.3 s, the 70% FOV coverage of the L1
is slightly better than a 64-line LiDAR
sensor.
B. As the integration time increases,
however, the FOV coverage of the L1
increases signicantly. After 0.8 s, almost
all areas are illuminated by laser beams
as the FOV coverage approaches
100%.
Repetitive Scanning Patterns
For the repetitive scanning method of L1, the scanning repeats approximately every 0.1 s, the horizontal
FOV is 70.4°, the vertical FOV is 4.5°, and the vertical angular resolution is slightly better than traditional
32-line LiDAR sensors.
Close Proximity Blind Zone: the L1 LiDAR sensor cannot precisely detect objects that are less
than 1 meter away. The point cloud data may be distorted to a varying extent when the target
object is within a range of 1 to 3 meters.
The range accuracy of L1 LiDAR is 2 cm tested in an environment at a temperature of 25° C
(77° F) with a target object that has a reectivity of 80% and is 20 meters away from the L1. The
actual environment may dier from the testing environment. The gure listed is for reference only.
