Abstract—As a fast and non-destructive detection technology, hyperspectral imaging technology has a wide range of applications in the field of automotive lighting. This paper introduces the principles of hyperspectral imaging technology and its current development status in miniaturization and intelligentilization. We discuss the application of hyperspectral and near-infrared spectroscopy in the field of automotive lighting, focusing on four key areas: driving terrain recognition, lighting systems based on environmental information, material characterization and quality control, durability and aging of lighting materials. It is detailed that hyperspectral and near-infrared technologies significantly improve the vehicle's environmental perception capabilities and enable efficient quality control and performance optimization of automotive lighting materials, playing a key role in the continuous advancement of intelligent vehicle systems.

Keywords-hyperspectral imaging; automotive lighting; autonomous driving; material analysis.
