these lidars will rotate to that same azimuthal position at every full second.
Trigger Method Time-Based(default)
Angle-Based
The way laser firings are triggered.
Angle-based Lasers fire every 0.2° at 10 Hz or 0.4° at 20 Hz.
Time-based Lasers fire every 55.56 us.
Noise Filtering OFF (default)
ON
To mitigate the scattered false positives (i.e. noise points) in point cloud data.
Interstitial Points
Filtering OFF (default)
ON
To mitigate the interstitial points.
Definition of interstitial points: when a beam partially hits on a front target's edge
and further hits on a rear target, the return signal can result in a false point
located between both targets.
Retro Multi-Reflection
Filtering OFF (default)
ON
To mitigate the false positives at twice the distance of a retroflector.
Reflectivity Mapping Linear (default)
Nonlinear Mapping 1#/2#
Linear The Reflectivity field in Point Cloud Data Packets
linearly represents target reflectivity (0 ~ 255%).
Nonlinear 1# and 2# Increases the contrast in low-reflectivity regions, see
Appendix IV (Nonlinear Reflectivity Mapping).
Standby Mode In Operation (default)
Standby
In Standby mode, the motor stops running and lasers stop firing.
