FMCW in-cabin 4D LiDAR demonstrated at CES 2025

Aeva® and Wideye, a division of AGC Group, have announced a joint demonstration of the first functional FMCW (Frequency Modulated Continuous Wave) in-cabin 4D LiDAR sensor for passenger vehicles at CES 2025.

The advanced integration of the Aeva Atlas™ 4D LiDAR sensor for behind the windshield placement combines the benefits of a high mounting position for enhanced long-range sensing with minimal impact on vehicle design and aerodynamics. Custom-formulated glass from Wideye, compatible with Aeva’s unique FMCW wavelength, increases infrared light transmission while maintaining LiDAR point cloud quality. Wideye glass benefits from high infrared transparency with nearly zero absorption, allowing the LiDAR sensor to deliver a high-end performance at full detection range.

Placing the LiDAR sensor behind the windshield protects from external elements and allows for easy cleaning of potential obstructions. Inside the cabin, the compact housing ensures road visibility while the sensor’s low power consumption and passive cooling support a quiet cabin and passenger comfort.

“As OEMs look to enable higher levels of safety and automation by incorporating LiDAR technology, we see the unique combination of Aeva’s powerful 4D LiDAR with Wideye Windshield is ready to meet their needs,” said Gaetan Friart, CEO at Wideye by AGC. “Placing the LiDAR behind Wideye windshield with other in-cabin optical sensors meets the stringent demands for next-generation vehicle autonomy without compromising on vehicle design.”

“LiDAR is quickly becoming a must-have sensing technology to enable higher levels of vehicle automation, including highway-speed driving,” said Mina Rezk, Co-Founder and CTO at Aeva. “This collaboration with AGC demonstrates that automakers can have the best of both worlds — a seamless and smooth industrial design that is powered by industry-leading 4D LiDAR from Aeva, without compromising on performance or safety.”
