Hesai Group, a LiDAR technology company, has launched its latest LiDAR solution for L2 to L4 autonomous driving, the Infinity Eye. Accompanying the new solution are three next-generation, automotive-grade LiDAR products: the ETX ultra-long-range LiDAR, the AT1440 ultra-high-definition LiDAR, and the FTX fully solid-state blind spot LiDAR.
The solution includes three configurations, Infinity Eye A, Infinity Eye B, and Infinity Eye C. Each one has been tailored to meet the necessary requirements of L4+ high-level autonomous (A) systems, L3 conditional autonomous driving (B), and L2 assisted driving (C).
Designed for L4 autonomous driving systems, Infinity Eye A combines four ultra-high-definition AT1440 LiDAR with four solid-state FTX LiDAR to offering full 360° coverage with no blind spots. This configuration provides both long-range and short-range detection, ensuring comprehensive awareness for autonomous applications like robotaxis and robotrucks. Powered by Hesai’s fourth-generation proprietary chip, it features 1,440 channels and a ranging capability of 300 meters at 10% reflectivity.
The AT1440 similarly utilizes high-efficiency photodetection and parallel processing technology, which Hesai says increases LiDAR channel count by 10 times compared to similar products on the market. Its point rate, which the company says exceeds 34 million points per second, similarly helps it to deliver over 45 times the point cloud density when compared to mainstream automotive LiDARs. This ultimately enables highly precise perception of small objects on complex urban roads, as well as subtle surface changes like bumps and dips.
Hesai expects the AT1440 to enter mass production in the second half of 2025, making its debut on Kargobot’s forthcoming transport robot, and is also set to be integrated into Kargobot’s mass-produced L4 autonomous truck platooning solution, supporting its large-scale commercialization.
A key component of the AT1440 is the FTX, a fully solid-state LiDAR that features an ultra-wide 180° x 140° field of view. While delivering more than twice the resolution of its previous generation, the new LiDAR sees a reduction in its exposed window area of 40%. The FTX supports the AT1440 by covering blind spots around the vehicle, while detecting low-profile obstacles such as curbs, pets, and other small objects, altogether enabling precise automated parking. Additionally, it can monitor fast-approaching vehicles from the rear and sides in real time, providing critical support for safe lane change decisions.
Hesai’s Infinity Eye B is tailored for L3 conditional autonomous driving systems, featuring a forward-facing, long-range ETX LiDAR alongside two of its FTX LiDAR sensors for blind-spot detection. This multi-LiDAR configuration aims to balance extended ranging capability with wide-angle field-of-view perception, altogether supporting core L3 driving tasks where the vehicle must take over in certain situations while allowing for human intervention.
The ETX, itself, is an automotive LiDAR designed for L3 with a long ranging capability. It can be mounted behind the cabin’s windshield and, with a compact 32 mm sensor window, offers a 400-meter range at 10% reflectivity. Using Hesai’s proprietary Photon Vector Technology, the sensor extends its ranging capabilities by 30% while maintaining Class 1 eye safety compliance, and reducing size and power consumption. Its angular resolution of 0.05° (H) x 0.05° (V), Hesai says, allows the ETX to offer eight times the resolution of its AT128 LiDAR. The company confirmed that it has secured multi-year nominations for the sensor from a leading European OEM, with mass production set to begin by the end of 2026.
Infinity Eye C is optimized for L2 ADAS, and features the compact, powerful, ATX LiDAR. Its 200-meter ranging capability at 10% reflectivity, up to 256 channels, and angular resolution of 0.1° x 0.1°, helps vehicles more accurately detect distant obstacles. Equipped with Hesai’s proprietary Intelligent Point Cloud Engine, the company says that the sensor can filter out over 99.9% of environmental noise, ensuring stable perception in a variety of weather conditions. Its compact design and ultra-low power consumption together allow for flexible integration into the vehicle body or behind the windshield, offering automakers greater flexibility in its installation.
While detailing these LiDAR innovations, Hesai also spotlighted its fourth-generation, proprietary technology platform, which offers enhancements in LiDAR performance, size, and manufacturability. By integrating advanced capabilities such as advanced photonic sensing and signal processing into a high-efficiency module, the new platform can deliver heightened point cloud density with lower power consumption requirements, which Hesai says can transform how LiDAR sensors are produced and delivered at scale.
The platform’s proprietary Intelligent Point Cloud Engine (IPE) decodes laser return waveforms with nanosecond-level precision, allowing it to process 24.6 billion samples per second. In adverse conditions such as rain, fog, dust, or exhaust, the IPE intelligently can filter out environmental noise, enabling all-weather perception with enhanced accuracy, ensuring reliable perception for autonomous driving systems.
