Abstract
A system for calibrating a laser cutting machine includes a calibration plate arranged to simulate a workpiece; a first quad photodiode (QPD) and a second QPD for converting light including an image of a portion of a surface of the calibration plate into a plurality of electrical signals, wherein the first and the second QPDs are positioned to receive the light propagated from the surface of the calibration plate through the optical path of the laser beam; and a control system for calibrating the laser cutting machine based on the plurality electrical signals.
