Abstract
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.
Claims4
A method, comprising:
- producing a fiducial source beam with an optical source;
- and
- using an optical fiducial pattern generator, producing with the fiducial source beam at least one transient optical fiducial on a laser processing target made of powder material that is in a field of view of a laser scanner situated to scan a laser processing beam across the laser processing target, wherein the optical fiducial pattern generator is coupled to the laser scanner so that a positioning of the laser processing beam with the laser scanner becomes adjustable relative to the positioning of the at least one transient optical fiducial in the field of view of the laser scanner.
