Abstract: The invention relates to a lithograph for production of digital holograms in a storage medium, comprising a light source (8) for generating a writing beam (10), driving means for two-dimensional displacement of the writing beam (10) relative to the storage medium (4) and with a first lens (16) for focussing the writing beam (10) on the storage medium (4) to be written to. The aim of the invention is to solve the technical problem of writing computer generated holograms as quickly as possible by means of optical lithography and with little complexity with simultaneous precise control of the positioning of the writing beam. Said aim is achieved, whereby a two-dimensional trigger matrix (18) is provided, means (20) for generation of a scanning beam (22) are provided, a second lens (24) for focussing the scanning beam (22) on the trigger matrix (18) is provided, the drive means (12, 14) moves the scanning beam (22) in two dimensions relative to the surface of the trigger matrix (18), the movement of the scanning beam (22) being coupled to the movement of the writing beam and means (26) for generating a trigger signal for controlling the intensity of the writing beam (10) are connected to the trigger matrix (18). The invention further relates to a method for production of digital holograms in a storage medium.

Abstract: The invention relates to a method for calculating a computer-generated hologram, whereby the dot distribution of the computer-generated hologram is calculated, the dot distribution of a macroscopic superstructure is calculated, and the dot distribution of at least one computer-generated hologram is combined with the dot distribution of the macroscopic superstructure to form a dot distribution to be written into a storage medium. The invention also relates to a method for writing the hologram, a storage medium, and a reading device. In this way, both a computer-generated hologram and a macroscopic superstructure that can contain directly readable information can be combined in the form of a dot distribution.

Abstract: 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. 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 to produce full or single colour rainbow white-light transmission holograms, achromatic white-light transmission holograms or single or full-colour white-light reflection holograms. Alternatively the same invention and apparatus permits the direct writing of full or single colour rainbow white-light transmission composite holograms, achromatic white-light transmission composite holograms or single or full-colour white-light reflection composite holograms without the need to pass through the intermediate stage of the H1 transmission hologram. The present invention allows the creation of a compact rugged machine that is capable of producing holograms covering a large size range. In addition the invention produces holograms that can be tiled together to form composite holograms much larger than the component panels.

Abstract: A hologram that can obtain high diffraction efficiency when reconstructed and is superior in productivity is provided. An arbitrary object image and a recording surface in which representative points are disposed with predetermined pitches are defined by use of a computer. At the position of each individual representative point, a complex amplitude for the wave front of object light emitted from the object image is calculated, and a complex amplitude distribution is calculated on the recording surface. This complex amplitude distribution is expressed by a three-dimensional cell having a groove in the surface thereof. Four kinds of groove depths are defined in accordance with the phase θ , and seven kinds of groove widths are defined in accordance with the amplitude A. Thereby, 28 kinds of three-dimensional cells in total are prepared, and a three-dimensional cell corresponding to the phase θ and amplitude A of the complex amplitude for the representative point is disposed at the position of each representative point. One of the 28 kinds of three-dimensional cells is disposed at the position of each representative point on the recording surface, and thereby a hologram-recording medium is formed as a set of three-dimensional cells. A reconstructed image is obtained by the phase/amplitude modulating function of the groove part of each cell.

Abstract: A diffractive device has a surface relief structure which, when illuminated by a light source, generates one or more diffraction images which are observable from particular ranges of viewing angles around the device. The device includes background diffractive structural elements and interstitial diffractive structural elements. The interstitial elements are interspersed between the background elements such that the diffractive action of the background elements is modulated by the interstital elements, with differing interstitial element configuration in differing parts of the surface relief structure producing differing diffraction effects in corresponding parts of the diffraction images.

Abstract: Methods for generating holograms from a computer model of any object (30) employ a combination of numerical and optical means. An illumination model and the light dispersion properties of the object (30) are specified. The hologram (50) is synthesized from a plurality of smaller hologram elements (52, 54). Each individual element (52, 54) sustains a field of view of the object. The light rays from the object lying within the field of view and along the lines of sight are sampled by the computer (60). The sample density should not exceed the resolution limit set by the size of the hologram element (50). Each light ray is specified by a direction and an amplitude function. The hologram element (52, 54) is obtainable from a Fourier Transform of the sampled rays. In one embodiment, optical means are employed to physically reproduce the sampled light rays using coherent radiation. The reproduced coherent light rays are then interfered with a coherent reference beam to form the hologram element (52, 54). Alternatively, the interference pattern is calculated directly by the computer (60) and is printed to form the hologram element (52, 54).
