Appl. No.:

10/008193

Inventors:

Brian J. Monaghan - Maple Glen PA
Anthony W. Heath - Lansdale PA

Assignee:

Illinois Tool Works, Inc. - IL

International Classification:

G03H 104

US Classification:

359 35, 359 1, 359 22, 359 25, 21912168, 21912169

Abstract:

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.

Appl. No.:

09/021281

Inventors:

Brian J. Monaghan - North Wales PA
Anthony W. Heath - Lansdale PA

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

G03H 102

US Classification:

359 27, 359 1, 359 2, 359 35

Abstract:

Holographic patterns are produced by utilizing a laser to illuminate a workpiece with an interference pattern, with sufficient laser power to ablate the workpiece where it is illuminated by the laser, and moving the workpiece and the interference pattern relative to each other.

Appl. No.:

8/452581

Inventors:

Brian J. Monaghan - Glenside PA

Assignee:

Pennsylvania Pulp and Paper Co. - Glenside PA

International Classification:

G03H 100
B31F 107
B29D 701
B41M 312

US Classification:

359 1

Abstract:

A substrate bears holographic imagery, selected portions of which are covered by non-holographic imagery printed in predetermined geometric registry with the holographic images. Multiple replicas of this interactive graphic work are mass-produced by embossing an array of the holographic imagery into a substrate in roll form, together with eyemarks located periodically along the roll. Using these eyemarks, the roll is optically sheeted and the non-holographic imagery then printed on the holographic substrate.
