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: 20090219596Abstract: 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. 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: May 15, 2009Publication date: September 3, 2009Applicant: VIEW HOLOGRAPHICS LTD.Inventors: David Brotherton-Ratcliffe, Florian Michel Robert Vergnes, Alexey Rodin, Mikhail Grichine

Patent number: 7333252Abstract: A method of writing a single or double parallax composite 1-step hologram is disclosed. Digital data is acquired from a real or virtual object and is described by a luminous intensity tensor. A single mathematical transformation is performed to convert the luminous intensity tensor into a mask tensor. The single mathematical transformation transforms the digital data whilst integrally correcting the digital data for the finite distortion of an optical objective. Corrected data, described by the mask tensor, is written on to a spatial light modulator. A laser beam is directed on to the spatial light modulator so that at least a portion of the laser beam is spatially modulated to form a spatially modulated laser beam. The spatially modulated laser beam is then passed through an optical objective having a finite distortion and in combination with a reference recording beam forms a composite hologram.Type: GrantFiled: January 27, 2003Date of Patent: February 19, 2008Assignee: XYZ Imaging, Inc.Inventors: David Brotherton-Ratcliffe, Alexey Rodin, Lynne Hrynkiw

Patent number: 7324248Abstract: A method and apparatus for producing holograms may use a computer generated 3-D model or data generated using multiple 2-D camera images taken of a real 3-D object or scene. The data is digitally processed and displayed on a high resolution spatial light modulator (SLM). A low energy pulsed laser records composite holograms on a holographic emulsion using a special optical design. Restricted or full parallax master transmission or reflection type composite holograms, known as H1 holograms, may be created that can be copied using traditional methods to produce full or single color rainbow white-light transmission holograms, achromatic white-light transmission holograms or single or full-color white-light reflection holograms.Type: GrantFiled: November 2, 2005Date of Patent: January 29, 2008Assignee: XYZ Imaging, Inc.Inventors: David Brotherton-Ratcliffe, Florian Michel Robert Vergnes, Alexey Rodin, Mikhail Grichine
