Light Detection and Ranging (LiDAR)

Light Detection and Ranging (LiDAR) is a remote sensing method that uses pulsed laser light to measure distances. While typically used in geological surveys and mapping to complement radar, LiDAR has become a critical technology for autonomous driving systems.
In the automotive sector, LiDAR systems are evolving from traditional mechanical spinning models to more durable and compact designs. Two key technologies driving this shift are Solid-state and MEMS LiDAR.

Solid-state LiDAR eliminates moving parts entirely by using semiconductor and optical technologies. Unlike conventional mechanical LiDARs that physically rotate the laser and detector, solid-state models are stationary. Although they typically have a narrower field of view, they are compact, robust, and easy to integrate into vehicle bodies. Using multiple sensors allows for full 360-degree coverage, making them an ideal choice for mass-produced vehicles.

MEMS (Micro-Electro-Mechanical Systems) LiDAR uses tiny mirrors to steer the laser beam. These mirrors tilt rapidly to scan the environment. Because the moving mass is negligible compared to mechanical motors, MEMS LiDAR offers faster scanning speeds and higher reliability suitable for automotive integration.
