Abstract
A method of manufacturing a master for producing a hologram device is provided. The holographic image reconstructs when the photosensitive film of the hologram device is struck by a beam of light from a wide angle being defined relative to a perpendicular line to a surface of the photosensitive film.
Claims12
A wide angle near-field illuminated hologram device comprising:
- a photosensitive film;
- and
- a holographic image of an object recorded in the photosensitive film or replicated copy of the same;
- wherein the holographic image reconstructs when the film is strike by a beam of light from a wide angle being defined as a predefined angle that falls within a range of +/−75 degrees to +/−90 degrees, inclusive, relative to a perpendicular line to a surface of the photosensitive film;
- wherein the holographic image is reconstructed when a light from a near field source, defined as a source that is positioned closer to the hologram than the largest dimension of the hologram itself, illuminates the photosensitive film at the wide angle.
A method of making a wide angle near-field illuminated hologram comprising of a converging lens system that records an orthoscopic image.
A method of making a wide angle near-field illuminated hologram comprising of a diverging lens system that records a pseudoscopic image.
