2.5 - Controlling Laser Material Processing with Real-Time Algorithms on Cellular Neural Networks

P. Strohm, A. Blug, D. Carl, H. Höfler, O. Krause & M. Panzner
Today image processing using a coaxial camera setup is used to monitor the quality of laser material processes such as laser welding, cutting, ablation or scribing. For real-time control of highly dynamic laser processes these systems are far to slow. This article proposes a sensing system for the next step: Using image based quality features in a real-time algorithm to form an instant feedback signal with up to 15 kHz in order to maintain the...
