QT Series
360° wide-angle short-range LiDARQT128 is a 128-channel LiDAR sensor that scans nearby objects with a wide vertical field of view. It supplies data for obstacle detection around vehicles and platforms in robotaxi, autonomous transport and logistics applications.
See your surroundings from a wider angle.
Wide vertical coverage
A 105° vertical field of view supports detection of nearby objects and obstacles at different heights.
Dense point cloud
Generates 1,152,000 points per second in single-return mode, delivering nearby environmental detail to perception software.
Compact body
The cylindrical body, 83.9 mm high, simplifies mounting plans on platforms requiring environmental sensing.
Distinguish objects with reflectivity data.
QT128 produces surface reflectivity information alongside distance data. This can be used for object recognition and evaluation of different surfaces.
