Hologram production technique

摘要

A system for forming holographic pixels on the surface of a workpiece is disclosed. The system comprises a laser generating a laser beam; a beam splitter dividing the laser beam into a first beam and a second beam; a controller providing as output at least one control signal; and at least one beam deflector receptive of the first and second laser beams guiding the first and second laser beams along different paths to a prescribed pixel location on the surface of the workpiece, thereby combining the first and second laser beams at a prescribed azimuthal direction and included angle. At least one beam deflector is receptive of the at least one control signal thereby controllably deflecting at least one of the first laser beam and the second laser beam to the prescribed pixel location.
