The reason eGaN FETs (and now ICs) are used in all the LiDAR systems for autonomous cars, and now autonomous race cars, is that they enable much higher resolution (due to extremely short laser pulses), faster image speed (due to short laser pulses), and the ability to see greater distances with high accuracy (due to fast laser pulses at very high current).

LIDAR is made up of a laser (or arrays) capable of transmitting pulsed light over the required range of interest, and a high-speed, low-noise receiver for reflected signal analysis. A portion of this light is reflected or scattered back to the receiver according to the reflectivity of the target.

EPC will exhibit live demonstrations showing how GaN technology’s superior performance is transforming power delivery for entire industries including computing, communications, and automotive.

EL SEGUNDO, Calif. — February 2018 — The EPC team will be delivering seven technical presentations on gallium nitride (GaN) technology and applications at APEC 2018 in San Antonio, Texas from March 4^th through the 8^th.

Developers are hard at work on the machine learning necessary for safer and more-autonomous vehicles. But all the AI in the world won’t be enough if the car relies on inadequate sensors. That was clearly demonstrated in one fatal Tesla crash that occurred in part because the car’s camera didn’t correctly identify an oncoming truck. To ensure smart vehicles have a reliable model of surrounding objects — particularly the ones the cars identify as “threats” — most rely on one or more lidars, or laser-based remote sensors.

This article takes a deep dive into lidar technology. It explains how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars.

The bottom line is that while bringing lidar costs down will take a significant amount of difficult engineering work, there don't seem to be any fundamental barriers to bringing the cost of high-quality lidar down below $1,000—and eventually below $100. That means the technology—and ultimately, self-driving vehicles that depend on lidar—should be well within reach for ordinary consumers.
