    Abstract: Apparatus and method for producing optically variable devices, optically variable media, dot matrix holograms or embossing substrates. The system includes: a laser beam generator, a laser beam shaper, a spatial light modulator, imaging optics and an image positioner. The laser beam generator generates a laser beam, which is shaped by the laser beam shaper to modify the laser beam to an optimized beam profile. The shaped laser beam is modulated by the spatial light modulator, which generates, at a place removed from the substrate surface, an optical pattern. The imaging optics causes the optical pattern to be imaged on the substrate surface. An image positioner allows for the optical pattern to be positioned to different areas of the substrate surface. The system can produce adapted optically variable devices, optically variable media, dot matrix holograms or embossing substrates.

    Abstract: This invention relates to an optical device and system for producing a holographic optical element or digital hologram. Various techniques of producing digital holograms have been proposed. However, they tend to suffer from long exposure times, as well as problems associated with control of two or more independent beams of coherent light used to produce a hologram. Problems become even more acute as pixel size decreases. The present invention provides an optical device including: a beam deflector (30), adapted to deflect a focussed or collimated beam of coherent light to produce an incident beam; a beam splitter (50) for producing first (12) and second beams (12b), said beams being displaced so that the angle of deflection of the first beam is the same but opposite to the angle of deflection of the second beam; and a beam combiner (55) that recombines the first and second beams so as to produce an interference pattern at an output plane (500). Another embodiment employs a mask aperture that forms a shaped pixel and an image reduction system.

    Abstract: An enhanced optical interference pattern, such as a diffraction grating, is incorporated into a photodefinable surface by shining three or more beams of coherent light from a single source at a photodefinable surface, such as a photosensitive emulsion/photoresist covered glass or an ablatable substrate and mapping the diffraction grating pattern to the photodefinable surface. Mapping of the optical interference pattern is created by interference of three or more light beams, such as laser light or other light sources producing a suitable spectrum of light. The mapped photodefinable surface can be used to create embossing shims. The embossing shim can then be used to emboss film or paper. The embossed film/paper can be metalized and laminated onto a substrate to create a product that has shifting patterns at a variety of viewing angles when exposed to white light.
