Abstract
An apparatus includes an optical source situated to produce a fiducial source beam, and an optical fiducial pattern generator situated to produce with the fiducial source beam 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, so that a positioning of the laser processing beam on the laser processing target becomes adjustable relative to the at least one transient optical fiducial.
