LASER WORKING SYSTEM FOR PERFORMING A WORKING PROCESS ON A WORKPIECE BY MEANS OF A LASER BEAM AND METHOD FOR MONITORING A WORKING PROCESS ON A WORKPIECE BY MEANS OF A LASER BEAM

摘要

The invention relates to a laser working system for performing a working process on a workpiece by means of a laser beam. The laser working system comprises: a laser working head for radiating a laser beam into a working region on the workpiece; and a sensor unit for monitoring the working process, the sensor unit having at least one hyperspectral sensor. The sensor unit is designed to capture a hyperspectral image of a region of the workpiece, the hyperspectral image having N times M pixels. The hyperspectral image has two spatial dimensions x and y and a spectral dimension λ. N indicates the number of pixels in the first spatial dimension x, M indicates the number of pixels in the second spatial dimension y, and L indicates the number of spectral bands in the spectral dimension λ of the hyperspectral image. M, N and L are natural numbers. The invention further relates to a method for monitoring a working process on a workpiece by means of a laser beam.
