LW20 / SF20 LiDAR sensor
Product manual
Changing the field of view does not affect the physical motion of the servo as this would upset the PWM and servo lag settings.
Instead, the field of view cuts out unwanted data from the edges of the scanned image. The left and right edge settings of the field
of view can be changed independently.

For high precision scanning, the servo can be made to scan in one direction only. The resulting image has higher angular repeatability
at the expense of increased power consumption by the servo when returning to the start of the scan. Switching from bi-directional to
uni-direction scans is done using the "Scan type" selection box.
