LW20 / SF20 LiDAR - Product manual - Revision 7
The LW20 is able to measure the first and last return signals when there is more than one
object in the laser beam.
Measuring the distance to the nearest object and the furthest object allows a drone to get
information about potential collisions with trees while simultaneously following the terrain at a
known height above ground.
The LW20 incorporates a laser encoding system that allows units to uniquely identify their own
signals. This prevents interference from other lasers that may be aiming at the same target
surface and makes it possible to run side-by-side redundant systems in safety critical
applications.
There are three different ways to communicate with the LW20:
For machine-to-machine communication there is a built-in command set that uses ASCII
•
mnemonics. These commands work via the serial or the I2C ports.
For human-to-machine communication there is an internal menu system that can be
•
accessed using a generic terminal application via the serial port. The LightWare Terminal
application can be used for this.
For interactive and graphical communication there is a GUI based Terminal application
•
available from the LightWare website. This application also uses the serial port.
