Abstract
The unique laser-matter interaction pathway in the ultrafast regime opens up many key potential applications in biology, electronics, optics, and beyond. However, upscaling local laser texturing on large and freeform surfaces remains a challenge for the deployment of the technology at an industrial level. In this concern, path planning [1,2] appears as a crucial preliminary step to succeed in an accurate and fast process. In the present work, we develop a methodology delivering an optimal scan path from a 3D point cloud on the surface to be laser treated. It can be implemented for any laser scanner embedded in a mobile head. The scan path is here defined by the sequence of target points centered in a 3D mesh adapted to the surface curvature, and calculated with surface normal, to obtain the positioning of the laser head in space for laser texturing the mesh cells, successively.
