This project is used for advanced driver assistance systems (ADAS)automatic driving. At present, our project will use a more sensitive CMOS single photon detector array to reduce the number of photons required for detection to less than ten, in order to break through the cost barriers of applications of LiDARestablish low-cost, high-performance LiDAR modules.

In this work, we demonstrate a dual multiplication layers In0.52Al0.48As based avalanche photodiode, which is desired for ToF lidarFMCW lidar application due to its high performances in both Geiger modelinear mode operations. By combining the specially designed mesa shape with dual M-layer structure, we can achieve high single photon detection efficiencyneat temporal characteristic of 65ps . On the other hand, we can also achieve high gain-bandwidth product ,high saturation currenthigh photo-generated RF power under 0.9 Vbr at the same time.

In this study, the embedded LiDARAI recognition of smart headlight for autonomous driving is demonstrated. At driving process, the vehicle can provide artificial intelligence to identify the type, distancespeed of the object to be measured based on the fusion data of the LiDAR point cloudoptical image of the environment,then feedback to the headlight control system. Finally, this smart headlight would perform the suitable lighting mode during the daynightfit the automotive lamp safety regulationsstandards (ECE R112SAE J3069).
