Periodic surface structures with micrometer or submicrometer resolution produced on surfaces of different technological parts can be used to improve their mechanical, biological or optical characteristics. While direct laser interference patterning (DLIP) already permits structuring speeds of up to 0.9 m2/min under constant process parameters, fabrication of individualized surface structures fabricated "on-the-fly" is not possible at high speeds. In this study, a scanner-based DLIP optical head is presented which combines the flexibility of the DLIP technology with a high-performance galvanometer scanner system. An evaluation of the structuring results as well as various application examples will be presented.

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.
