SF30
Accelerated rangefinder
The SF30 is a high speed, light weight
laser rangefinder for mapping and
obstacle detection by robotic
vehicles such as UAVs.
The SF30 can take up to 36633
readings per second and can be
incorporated into scanning systems to
create 2D SLAM maps or 3D images.
The configurable features and
multiple hardware interfaces make
the SF30 easy to connect with
different types of controllers.
The SF30 uses a time-of-flight system
to make very fast and accurate
distance measurements to natural or
artificial surfaces.

There are two members of the SF30 family: the SF30/B has a maximum measuring range of 50 meters; and the SF30/C has a maximum measuring range of 100 meters. Both SF30 models have settings to smooth the distance measurements if higher resolution is required or use the raw results if higher speed is needed. -

4. Communicating with the USB port The SF30 has a micro-B USB port that can be used to communicate with LightWare Terminal software on a PC. This connection also gives power to the unit providing a quick way to test and configure the SF30. The LightWare Terminal software will automatically detect the USB port that is connected to the SF30 and communications can be established by clicking on the “Connect”... -
