Smart Headlights with Coaxial Integration of LiDAR and Radar Sensing

Increasing complexity of driving environments requires advanced sensing technologies to enhance vehicle safety and automation. Our study presents the design and implementation of a smart car headlight demonstrator that integrates LiDAR and radar sensing modules in a compact, coaxial configuration alongside low- and adaptive driving beam functionalities. The lighting modules are based on maskless double-sided microlens arrays, which provide a compact yet efficient solution capable of achieving the required beam brightness despite losses incurred by the combiners. By embedding the sensing path coaxially with the lighting beams, we aim to streamline overall design and improve overall system compactness and efficiency while allowing for high design freedom in the aesthetic appearance of the headlight.
