摘要： 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 holograms without the need to pass through the intermediate stage of the H1 transmission hologram.

摘要： A compact 1-step holographic printer is provided comprising one or more diode- pumped pulsed lasers (101). Inexpensive and compact micro-lens arrays or equivalent holographic optical elements (109) are used in conjunction with one or more spatial light modulators (108) to generate one or more object beams encoded with suitable digital image data. One or more variable-angle reference beams are used to write simultaneously one or more holographic pixels. Use of photopolymer recording material (110) enables rapid printing of high quality 1-step full-colour reflection holograms within a compact unit with no chemical processing.

摘要： 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.

摘要： 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.
