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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
