  • Patent number: 10895743
    Abstract: The present invention relates to a display apparatus for superimposing a virtual image into the field of vision of a user of the display apparatus, having spectacles for the user and at least one projection device for producing light rays which are transferred by means of an optical unit of the spectacles into a beam path which produces a virtual image for the user. The optical unit may comprise a ground-glass screen or lens array and a holographic optical imaging unit. The ground-glass screen or lens array and holographic optical imaging unit are arranged in such a way that the light rays produced by the projection device are incident on the holographic optical imaging unit through the ground-glass screen or the lens array and are transferred by the holographic optical imaging unit into the beam path which produces the virtual image for the user.

  • Patent number: 10031480
    Abstract: When coating a document surface (3) having relief-like information (1) carrying personal data, for example, with a monomer-containing liquid UV adhesive (4) across the entire surface and then laminating thereon a volume hologram (2), the varying adhesive thicknesses between the volume hologram and the document surface resulting from the relief cause differentiated swelling and thereby a differentiated color shift of the hologram. After the desired color shift is achieved, the UV adhesive (4) is completely cured. In this way, individual holographic information is obtained, which is located exactly above the relief-like information of the document. With this method, holographic overlays comprising personal data and a passport picture can be produced, and it is possible to link defined optical document information to the hologram in an accurately positioned manner, so that information is visible both non-diffractively and, from a different viewing angle, holographically in a different color.

  • Patent number: 9744793
    Abstract: According to one aspect, the invention relates to an optical safety component having a plasmonic effect intended to be observed by transmission, including two layers (101, 103) made of a transparent dielectric material, a metal layer (102) that is arranged between said layers made of dielectric material to form two dielectric-metal interfaces (105, 106), and is structured to form on at least a portion thereof corrugations (104) that are capable of coupling surface plasmon modes supported by said dielectric-metal interfaces with an incident light wave. The corrugations are arranged in a first coupling area in a first main direction and in at least one second coupling area separate from said first coupling area, in a second main direction that is substantially perpendicular to said first main direction, said metal layer being continuous on each one of said coupling areas.

  • Patent number: 9104176
    Abstract: The invention relates to a method for the production of a multicolor hologram by means of a capture beam, wherein the utilized capture beam (6) has a plurality of beam bundles of the same wavelength. Advantageously, the multicolor hologram is produced by copying the structure of multiple single-color subholograms of a master hologram (1) in a copy layer (5) which is affixed parallel to the master hologram, by illuminating this copy layer with the single-color capture beam. Each beam bundle appears at a prespecified angle of incidence, wherein the angles of incidence are calculated in such a manner that the structure of a corresponding subhologram is produced in the copy layer. In this way, a falsification is nearly impossible.

  • Patent number: 8810766
    Abstract: A method and a device are described for producing copies/replica of a volume reflection hologram wherein a holographic film (4) is guided over a drum with polygon cross-section having at least two planar (polygon) master surfaces (3) to each of which at least one master (7) is attached in the circumferential direction, where the film is brought into contact with at least one master hologram (7) and its entire surface is exposed to laser. It is essential that to at least one of the master surfaces (5) with the film guided over it, a laser exposure unit (22) is assigned which allows full exposure of the respective master surface to parallel, coherent laser beams (6), and that the at least one exposure unit (22) follows section wise the rotational movement of the drum by a splitting angle with equal velocity and exposes the corresponding master surface (5) to then be reset quickly again and perform the same angular displacement and exposure together with the next master surface.

  • Patent number: 8599458
    Abstract: A method and an apparatus are described for producing a volume transmission hologram and/or a volume reflection hologram from a film (10) having a backing foil (12) and a holographic layer (14). In said method, the film (10) is guided over a drum (18), on which the film (10) is brought in contact with the master hologram (22). The master hologram (22) and the film (10) are simultaneously moved through an exposure zone (20). In the exposure zone (20), the film (10) and the master hologram (22) are irradiated with a linearly expanding exposure laser beam (32) in order to reproduce the master hologram (22) in the photopolymer layer (14). Both volume reflection and volume transmission holograms can be produced in the polymer layer (14) of the film (10) that is guided over the drum by means of only one drum (18).

  • Patent number: 8263292
    Abstract: A production method is provided by which a copied volume hologram from a multi-layer master is later customized by utilization of the color tuning properties of the light-curable materials used for the application onto personal documents. These holographic individual data, such as a passport photo, are also separately detectable, without the holographic elements copied from the master, that are visible under other viewing angles, impairing the visibility of the individual data. The volume hologram overlay obtained by this method is applied on personal and valuable documents to increase protection against forgery, possesses superimposed optically variable items of information that are separately visible under different viewing angles and give a defined color change under different view angles, wherein at least one of these items of optical information represents individual personal data, in particular a passport photograph.

  • Patent number: 8059320
    Abstract: In a method for production of documents with a hologram and a document with a hologram, wherein, in a first step, a hologram is exposed in a photographic film and, in a second step, the photographic film is applied to a document support, the individualisation of the holograms first occurs during the gluing or after the gluing to the printed personal document or to the protective film provided for the surface protection of the document. It is thus possible to produce in a secure and economical fashion documents with individual holographic information of greater visibility and with further novel security features.
