LiDAR (Light Distancing and Ranging)

LiDAR

LiDAR (Light Distancing and Ranging) uses pulsed lasers to rapidly create a three dimensional image or map of a surrounding area. LiDAR technology allows for high accuracy, larger coverage areas, and increased speed and efficiency of data collection. The technology has traditional applications in mapping, coastline management, geological surveys, meteorology, and natural resource exploration.

Today's eGaN® FET’s ability to switch ten times faster than the aging power MOSFET gives LiDAR systems superior resolution and faster response time. The sharp switching transitions that are possible with eGaN FETs enable greater accuracy. These characteristics enable new and broader applications for LiDAR such as real-time motion detection for video gaming, computers that respond to hand gestures, and fully autonomous vehicles.
