SCANNER FOR INDUSTRIAL LASER MACHINES

摘要

SCANNER FOR INDUSTRIAL LASER MACHINES Disclosed is a scanner for industrial laser machines, which comprises a housing accomodating a movable scanning element, a means for inducing mechanical oscillations of the scanning element, which is connected to the housing, and a measuring transducer responding to the mechanical oscillations of the scanning element. At least two collision pairs are connected with the housing and the scanning element. The measuring transducer is connected to a phase shift unit coupled to a saturation unit. The means for inducing mechanical oscillations of the scanning element and the saturation unit are connected to a power amplifier.
