Abstract
Cette invention concerne un dispositif de commande de traitement laser, faisant intervenir une pluralité de fibres optiques (36), destinées à surveiller différentes parties (37) d'une zone de soudure. Les signaux individuels sont combinés afin d'offrir un certain nombre de modes de commande possibles, telles que la mise au point, l'écartement, le suivi de la ligne de soudure et le contrôle de la vitesse. Ces signaux peuvent être utilisés comme entrées dans des systèmes à logique floue ou d'autres systèmes de commande de laser.
