Beschreibung
Zusammenfassung:	A method includes producing a fiducial source beam with an optical source, and forming at least one transient optical fiducial on a laser processing target that is in a field of view of a laser scanner situated to scan a laser processing beam across the laser processing target, with an optical fiducial pattern generator that receives the fiducial source beam, to adjust a positioning of the laser processing beam relative to the at least one transient optical fiducial.
