Headlamp with LiDAR integration to be shown at CES
Silicon photonics startup SiLC Technologies (Monrovia, CA) and global exterior vehicle lighting systems company Varroc Lighting Systems have announced they will demonstrate a seamless lidar integration into a production automotive headlamp at CES 2020.

The headlamp, say the companies, is based on a sophisticated production LED design and leverages four of SiLC's silicon photonics frequency modulated continuous wave (FMCW) lidar vision chips providing a full 20 x 80-degree field of view (FOV) per headlamp. SiLC's compact lidar chip architecture is claimed to be able to be inconspicuously embedded anywhere on a vehicle for optimal vision and safety.

The 4D+ Vision Chip, says the company, integrates all required functionality - such as a coherent light source and optical signal processing - to enable significant additional information to be extracted from the returning photons before their conversion to electrons. The sensor can detect height, width, distance, reflectivity, velocity, and light polarization of objects.

The coherent interferometric sensing approach, says the company, improves achievable accuracy by orders of magnitude over existing technologies. The 4D+ Vision Chip can detect low reflectance objects beyond 200 meters surrounding a vehicle, providing enough time for a vehicle to avoid an obstacle at highway speeds.

"SiLC is excited to showcase its 4D+ Vision Chip at CES 2020 in partnership with Varroc Lighting Systems, and demonstrate the accuracy, range and elegance of embedded FMCW lidar in an automotive application," says SiLC CEO Dr. Mehdi Asghari. "Our integrated lidar chip offers the most compact, cost-effective, eye-safe and accurate lidar solution available to meet autonomous vehicle safety and affordability requirements."

The demonstration at CES will take place at SiLC's Westgate Hotel penthouse suite from Tuesday, January 7 through Friday, January 10.
