Patent number: 7983316Abstract: A pulsed multiple color laser system is disclosed having particular application for incorporation into a digital holographic printer for producing RGB color reflection holograms. A Nd:YLF crystal 1 in a laser cavity is excited to produce an emission at 1313 nm which is frequency converted by doubling to 656.5 nm and by tripling to 437.7 nm. In a separate cavity a similar Nd:YLF crystal 1a is synchronously or asynchronously excited to produce an emission at 1047.1 nm (or at the related line of 1053 nm) which is frequency converted by doubling to 523.6 nm (or 526.5 nm). The emissions at 437.7 nm and 656.5 nm are combined co-linearly with the emission at 523.6 nm (or 526.5 nm) to produce a single RGB pulsed laser beam.Type: GrantFiled: February 23, 2010Date of Patent: July 19, 2011Assignee: Geola Technologies Ltd.Inventors: Alexey Rodin, Florian Vergnes, David Brotherton-Ratcliffe

Publication number: 20070070479Abstract: A single method and apparatus for producing many of the most common types of hologram from digital data is disclosed. The data are generated entirely by a computer as a 3-D (animated) model or from multiple 2-D camera images taken of a real 3-D (moving) object or scene from a plurality of different camera positions. The data are digitally processed and displayed on a small high resolution spatial light modulator (SLM). A compact low energy pulsed laser, is used to record composite holograms. The present invention permits the creation of restricted or full parallax master transmission or reflection type composite holograms, known as H1 holograms, that can be copied using traditional methods.Type: ApplicationFiled: September 26, 2006Publication date: March 29, 2007Inventors: David Brotherton-Ratcliffe, Florian Vergnes, Alexey Rodin, Mikhail Grichine

Publication number: 20070030544Abstract: A single method and apparatus for producing many of the most common types of hologram from digital data is disclosed. In one embodiment the data are generated entirely by a computer as a 3-D (animated) model. In another embodiment the data are generated from multiple 2-D camera images taken of a real 3-D (moving) object or scene from a plurality of different camera positions. The data are digitally processed and displayed on a small high resolution spatial light modulator (SLM). A compact low energy pulsed laser, which avoids the usual vibration problems encountered at high rates of production and the installation in normal working environments, is used to record composite holograms on an holographic emulsion using a special optical design.Type: ApplicationFiled: November 2, 2005Publication date: February 8, 2007Applicant: XYZ Imaging, Inc.Inventors: David Brotherton-Ratcliffe, Florian Vergnes, Alexey Rodin, Mikhail Grichine

Publication number: 20060126682Abstract: A pulsed multiple colour laser system is disclosed having particular application for incorporation into a digital holographic printer for producing RGB colour reflection holograms. A Nd:YLF crystal (1) in a laser cavity is excited to produce an emission at (1313) nm which is frequency converted by doubling to 656.3 nm and by tripling to 437.7 nm. In a separate cavity a similar Nd:YLF crystal (1a) is synchronously or asynchronously excited to produce an emission at 1047.1 nm (or at the related line of 1053 nm) which is frequency converted by doubling to 523.6 nm (or 526.5 m). The emissions at 437.7 nm and 656.5 nm are combined co-linearly with the emission at 523.6 nm (or 526.5 nm) to produce a single RGB pulsed laser beam.Type: ApplicationFiled: December 23, 2005Publication date: June 15, 2006Inventors: Alexey Rodin, Florian Vergnes, David Brotherton-Ratcliffe

The present invention permits the creation of restricted or full parallax master transmission or reflection type composite holograms, known as H1 holograms, that can be copied using traditional methods. Alternatively the same invention and apparatus permits the direct writing of hologram without the need to pass through the intermediate stage of the H1 transmission hologram.Type: ApplicationFiled: February 11, 2005Publication date: September 15, 2005Applicant: XYZ Imaging, Inc.Inventors: David Brotherton-Ratcliffe, Florian Vergnes, Alexey Rodin, Mikhail Grichine
