ABSTRACT This paper focuses on the development of LiDAR technology, which plays an important role in fields such as automobile autonomous vehicles and advanced driver assistance systems (ADAS). LiDAR recognizes objects around the vehicle by providing higher precision and spatial resolution than other autonomous sensors, but unlike other sensors, it cannot penetrate metal. Therefore, it is mounted in a form exposed to the grill or covered with a black cover. In this case, there is a problem that the transmittance drops by more than 3-50% when impact or scratch occurs due to external influences. To solve this problem, this study presented a technical solution to ensure LiDAR performance by combining near-infrared transmission metallic film, permeable black polycarbonate (PC) and the self-restoration function of polyurethane.
