7.2 Phase Lock
When using multiple RS-LiDAR-32 sensors in proximity to one another, users may observe interference
between them due to one sensor picking up a reflection intended for another. To minimize this
interference, RS-LiDAR-32 provides a phase-locking feature that enables the user to control where the
lase firings overlap.
The Phase Lock feature can be used to synchronize the relative rotational position of multiple sensors
based on the PPS signal and relative orientation. To operate correctly, the PPS signal must be present
and locked. Phase locking works by offsetting the rising edge of the PPS signal.
Figure 12: Phase Offset 0°/135°/270°.
The red arrows in Figure 12 above indicate the firing direction of the sensor’s laser the moment it
receives the rising edge of the PPS signal.
In the Tools > RS-LiDAR Information of RSVIEW, we can set the Phase Lock angle from 0 to 359.
The phase lock function requires the rotate speed to be set up at 600 or 1200 rpm.
