Abstract

A workpiece processing machine that includes: a beam emission head for providing a beam for processing the workpiece, an optical interferometer for splitting, redirecting, and detecting the beam, an adjustment element for changing a second portion of a power of the beam redirected from a retroreflector to a detector, and a control unit for actuating the adjustment element to control a ratio between a first power portion of the beam redirected from the workpiece to the detector and the second power portion of the beam redirected from the retroreflector to the detector to a target ratio.
