“…We conclude, that the detection of the position of process radiation during laser welding does indeed seem to be feasible within reasonable ranges of resolution. Our work therefore will continue with improvements of our Optical Nozzle design [ 2,[4][5][6][7]9], which incarnates a 3D-position sensor used to track the coordinates of the center of process emissions during laser machining. These coordinates found Table 1) caused by one emitter moving from location p a to p b (left diagram) or by a second emitter moving from location p a ?…”

Sensing position is of fundamental relevance to production systems, which deal with the adjustment and control of shape and placement. An arrangement of 2, 4, or 8 optical fibers can be used to track the 1D-, 2D-or 3D-position of a light spot or optical emitter. Non-complex signal processing as well as far reaching independence of the measurement function from emitter intensity add to the attractiveness of our sensor design. This work will expand on the design's theoretical basis and will conclude with a simulation of the measurement error introduced by size and shape variations of the emitter. Such variations can occur when tracking curved surfaces or emitters of unknown shape such as the process radiation during laser machining.

Das Laserstrahlschweißen hat sich in den vergangenen zwei Jahrzehnten zu einer Schlüsseltechnologie entwickelt. Das gilt insbesondere für den Fahrzeugund Anlagenbau (Abb. 1), aber auch für die Elektronikfertigung und die Feinwerktechnik. Hohe Flexibilität, hohe erreichbare Geschwindigkeiten und herausragende Schweißnahteigenschaften (bei gleichzeitig geringem Wärmeeintrag) haben zu einer Vielzahl von industriellen Anwendungen sowohl im Mikro‐ als auch im Makrobereich geführt.
