TiM351 2D LiDAR sensor

•
One or two 2D LiDAR sensors detect their surroundings by scanning them two-
dimensionally using the time-of-flight method.
•
To do so, a laser beam is emitted, and a moving mirror is used to guide it in the
required direction.
•
The laser beam is emitted through the front screen. The scan plane position is
indicated by a housing marking next to the front screen.
•
When the laser pulse hits an object, it is reflected and sent back to the receiver of the
2D LiDAR sensor.
•
By calculating the time difference between sending and receiving and the signal
strength, the position of the object is detected with millimeter precision and forwarded
to the internal field evaluation unit of the 2D LiDAR sensor.
