Figure: Scan angle in repetitive scanning mode
Non-repetitive scanning pattern: The FOV is 70°×75°. This scanning mode features a wide scan
range, which can obtain more facade information. This mode is recommended for taking photos of
complex structures, such as the facades of a building.

Note:
The effective detection range of Zenmuse L2 varies based on where the object is within the FOV.
The closer to the edge of the FOV, the shorter the effective detection range. The closer to the
center of the FOV, the longer the effective detection range.
2.3.5. Beam Divergence
A divergence angle, if any, of the beams from the LiDAR can produce light spots which increase
in size as the distance increases.
2.3.6. Ranging Accuracy
Ranging accuracy refers to the gap between the LiDAR measured distance and the actual distance.
Ranging accuracy is different from system accuracy in that the former does not represent the
accuracy of the final result.
2.3.7. IMU Calibration
The accuracy of the Inertial Navigation System is gradually degraded when the aircraft is flying at
a consistent speed. In the case of Zenmuse L2, after the aircraft flies at a consistent speed for 200
seconds, the accuracy of the Inertial Navigation System drops below the nominal accuracy. With
IMU Calibration, as long as there is a rapid speed change within a short period of time, the accuracy
can be restored to a high level.
