Definition

Light detection and ranging sensors for mapping and perception

Technologies

Solid-state LiDAR eliminates moving parts for automotive reliability. FMCW LiDAR measures velocity simultaneously with distance. Flash LiDAR captures entire scenes in single pulses. Photon counting achieves long range with eye-safe power levels. Software-defined LiDAR adapts scanning patterns to driving conditions.

Applications

Autonomous vehicles use LiDAR for 3D perception and obstacle detection. Drones create topographic maps and building models. Industrial robots use LiDAR for navigation and object detection. Forestry management measures tree height and density. Archaeological surveys reveal hidden structures.

Market and funding

The global LiDAR market exceeded $3 billion in 2025, with automotive, mapping, and industrial applications driving growth.
