Abstract

Laser-scanner headlamps, based on a blue laser spot steered by a MEMS mirror over a converter, can illuminate the road flexibly and efficiently. Some existing demonstrators suffer from insufficient performance of the converter (low contrast) or of the MEMS mirror (lack of flexibility). With a new high-contrast converter and highperformance MEMS mirrors, we have developed improved laser-scanner demonstrators optimized for different functions like full adaptive driving beam or visualization (symbols, guiding lines, and text). We explain the system design, converter technology, and high-bandwidth MEMS control, show the performance in video sequences, and discuss future applications of such systems.
