Abstract

Reproduction of volume holograms. The invention relates to the reproduction of holographic photographs throughout the thickness (very mass) of materials of the plastic, compounds (derivatives) or glass type. There is direct inclusion, at the time of casting or moulding, by a system of positive (father) or negative (mother) mould bottoms obtained by "electroforming" or electrical discharge machining and making it possible to reproduce a holographic photograph of objects, of persons or of any other thing which can be filmed. This method according to the invention makes it possible to create new industrial opportunities by manufacturing either surfaces or volumes or parts of these with a so-called grating hologram or photograph.

Description

La présente invention permet dans la masse même des produits, la fabrication, la reproduction, la duplication de prise de vue holographique par la réalisation d'une matière et/ou d'un état de surface à capacité diverses de diffraction du spectre lumineux. The present invention allows in the very mass of the products, the manufacture, the reproduction, the duplication of holographic shooting by the production of a material and / or of a surface state with various capacity of diffraction of the light spectrum.

L'Holographie fut découverte en 1947 par Denis Gabor (prix nobel de physique en 1971). En 1961 le laser permit d'obtenir les premiers hologrammes en lumière cohèrente indis pensable pour coder les informations sur un support photographique en particulier 1' information de "phase" qui correspond à la notion de distance et permet de restituer le volume de l'objet. Holography was discovered in 1947 by Denis Gabor (nobel prize in physics in 1971). In 1961 the laser made it possible to obtain the first holograms in coherent light essential to code the information on a photographic support in particular the information of "phase" which corresponds to the concept of distance and makes it possible to restore the volume of the object .

Aujourd'hui la reproduction des Hologrammes 2D ou 3D en série se fait uniquement par estampage apellé aussi embossage. Cette fabrication est limitée à la production d'images holographiques uniquement sur supports autocollants ou destinés à être déposés à chaud. Today the reproduction of 2D or 3D Holograms in series is done only by stamping also called embossing. This production is limited to the production of holographic images only on self-adhesive supports or intended to be deposited hot.

La grande nouveauté de cette méthode de fabrication réside dans les divers débouchés industriels qu'elle concerne étant donné qu'elle inclus directement la reproduction dans la masse même des produits fabriqués. The great novelty of this manufacturing method lies in the various industrial outlets that it concerns, since it directly includes reproduction in the mass of the products produced.

La technique eihployée à partir d'un "photo-resist" ou prise de vue holographique sur plaque sensible spéciale, consiste à obtenir par une phase "électroformage" (electrolyse par nickel) une surface dite "de fond de moule" négative ou positive. The technique used from a "photo-resist" or holographic shooting on a special sensitive plate, consists in obtaining by a phase "electroforming" (electrolysis by nickel) a surface called "bottom of mold" negative or positive.

Le principe est de mouler sur cette empreinte de fond de moule un dérivé plastique ou du verre ce qui permet d'obtenir en totalité ou partiellement sur sa surface ou dans sa matière cette reproduction d'hologramme. The principle is to mold a plastic or glass derivative onto this mold base imprint, which allows this hologram reproduction to be obtained in whole or in part on its surface or in its material.

I1 est de même possible de créer grace à.une prise de vue de réseau un état de surface ou de matière ayant la capacité de diffracter la lumière. It is likewise possible to create, thanks to a network shot, a state of surface or of material having the capacity to diffract light.

Ces deux opérations sont soit combinées soit utilisées de façon indépandantes l'une de l'autre.These two operations are either combined or used independently of each other.

La diversification des unités et des techniques de moulages du verre ou des dérivés plastiques permet la réalisation de la quasi totalité des objets usuels, de décoration ou utilitairesconnus aujourd'hui.  The diversification of units and molding techniques for glass or plastic derivatives allows the realization of almost all the usual objects, decoration or utility known today.

Il est à noter la possibilité de mêtalisation d'une des faces des différents produits obtenus; de coloration des matières pour obtenir différents effets; la forme concave ou convexe pouvant être adoptée pour accentuer ou rétrécir la lecture. It should be noted the possibility of metalizing one of the faces of the different products obtained; coloring of the materials to obtain different effects; the concave or convex shape can be adopted to accentuate or narrow the reading.

La grande technicité des différents moyens mis en oeuvre, permet de rendre infalsifiables des productions ou parties de celles-ci incluant ce procédé ou utilisant des pièces produites par ce procédé. The great technicality of the various means used, makes it possible to make tamper-proof productions or parts thereof including this process or using parts produced by this process.

Applications . industrielles: La fabrication industrielle de toutes sortes de produits reproduisant un hologramme, un jeu ou effet de réseau reproduisant un décor ou aspect de surface. La fabrication et la mise en oeuvre de tous procédés incluant une prise de vue holographique en moulage, injection, thermoformage, plasturgie en général avec ou sans métallisation des pièces obtenues. Applications. industrial: The industrial manufacture of all kinds of products reproducing a hologram, a game or network effect reproducing a decoration or surface appearance. The manufacture and implementation of all processes including a holographic shot in molding, injection, thermoforming, plastics in general with or without metallization of the parts obtained.

Ces applications portent par exemple sur : des accessoires de mode, des objets utilitaires de décoration, des accéssoires de mobilier, des revêtements de mobilier ou de décoration, des objets de conditionnement.  These applications relate for example to: fashion accessories, decorative utility objects, furniture accessories, furniture or decoration coatings, packaging objects.
