Aim of this work is to provide a contribution to the system technology for focus position control during laser beam welding by a new sensor system and a new actuator system. In the conducted work the conception, theoretical fundamentals and the realization of a transmissive, active lens (TAO) and a distance sensor based on active triangulation are presented. Experimental investigations of the real properties of these novel system components for distance-controlled laser beam welding verify the theoretical results and allow together with additional simulations and models a comprehension of the complex dependencies between the laser beam or the laser welding process respectively and the novel system components.
