AT128
120° high-resolution long-range LiDARAT128 is a long-range LiDAR sensor that detects the environment ahead of vehicles in detail with 128-channel scanning. Its 120° field of view and high point rate provide three-dimensional environmental data to ADAS and autonomous-driving software.

Range and detail for vehicle perception.
128-channel sensing
Uniformly distributed vertical channels help evaluate objects such as vehicles and pedestrians.
Wide forward field of view
A 120° horizontal and 25.4° vertical field of view covers the area ahead with a single sensor's scan.
High point density
1,536,000 points per second in single-return mode and 1200 × 128 pixel resolution produce a detailed point cloud.

Dense sampling for small objects.
Angular resolution of 0.1° horizontally and 0.2° vertically supports detailed evaluation of vehicles, pedestrians and other roadside object geometry.
