Gallium Nitride Lidar (Light Distancing and Ranging)

Lidar (Light detection and ranging)

See Farther • See Faster • See Better

Lidar is a method for measuring distance using pulsed lasers. The information gained from the time-of-flight lidar system can be used to create a three-dimensional image. Lidar technology allows for high accuracy, larger coverage areas, and increased speed and efficiency of data collection.

eGaN® FETs and ICs are the logical choice to use for firing a laser because the FETs can be triggered to create high-current pulses with extremely short pulse widths. The short pulse width leads to higher resolution, and the higher pulse current allows lidar systems to see farther. These two characteristics, along with their extremely small size, make GaN ideal for lidar.

Thus, lidar systems with GaN can see farther, faster, and better.
