Abstract
Some embodiments may include a galvanometric laser system, comprising: a laser device to generate a laser beam; an X-Y scan head module to position the laser beam on a work piece, the X-Y scan head module including a laser ingress to receive the laser beam and a laser egress to output the laser beam; a support platen located below the laser egress; an in-machine imaging system integrated with the galvanometric laser, wherein a camera of the in-machine imaging system is arranged to view a surface of an object located on the support platen using one or more optical components of the X-Y scan head module to generate assessment data associated with a calibration of the X-Y scan head module by imaging the surface of the object, wherein a calibration fiducial is located on the surface of the object.
