    摘要: The invention relates to a method and to a device (1) for producing a hologram, in particular as a security feature, and to a hologram. The invention further relates to a method for producing an individualised hologram in which coherent light (8) is generated and is modulated spatially according to an individualised pattern. Said modulated light (11) is used, preferably, to expose a hologram in such a manner that the holographic recording material (4) is radiated by the coherent modulated light (11) and at least one part of the coherent light (11) is reflected or refracted on a holographic master (2) in order to interfere with the coherent light (11) radiating the holographic recording material (4) such that the hologram in the recording material (4) is exposed. The invention is characterised in that, by means of the hologram master (2), a background pattern stored in the hologram master (2) is stamped on the modulated coherent light comprising the coded individualised information when reflecting or refracting on the hologram master (2), such that the background pattern is stored together in the hologram with the individualised information.

    摘要: The invention relates to a method for writing holographic pixels in a holographic recordable film (3), comprising a photo component that can be changed photochemically and/or photophysically by exposure, wherein the holographic recordable film (3) is positioned above a reflection master (4), wherein a primary light beam (P) is directed at the holographic recordable film (3), wherein the primary light beam (P) penetrates the holographic recordable film (3) and is reflected by the reflection master (4) to form a reflection light beam (R). The primary light beam (P) and the reflection light beam (R) interfere in the holographic recordable film (3) within an interference zone (10) and change the photo component in the interference zone to form the holographic pixel. The method is characterized in that a transmission hologram (6) is arranged between the holographic recordable film (3) and the reflection master (4) and that the transmission hologram (6) diffracts the primary light beam (P) and/or the reflection light beam (R) with the proviso that the interference zone (10) has a larger lateral surface area, in relation to the directions orthogonal to the surface normal for the holographic recordable film (3), than in the absence of the transmission hologram (6).

    摘要: A multilayer thin film filter is disclosed an organic dielectric layer (104) serving as a spacer layer in a Fabry-Perot structure. The dielectric has embossed regions of varying thicknesses wherein the thickness within a region is substantially uniform. Each different region of a different thickness produces a different color (C1, C2, C3) (shift). The size of one of the embossed adjacent regions is such that the color (C1, C2, C3) of said one region is uniform and cannot be seen by a human eye as different in color from the uniform color of an adjacent region thereto, and wherein the color within a region can be seen with magnification of at least 10:1. This serves as a covert color coding system useful as a security device.

    摘要: A holographic display includes "segmented" images (24) configured as if positioned in separate viewing "cells" (28, 28 a corresponding spatially to preselected subareas of a desired display area with invisible segmenting cell sides. Constantly viewable unsegmented holographic images recorded in the same recording medium (16′) as the segmented images or on a separate recording medium can be multiplexed into the display area using a conjugate light source (50) of a different frequency or having a different polarization condition (e . g., unpolarized) from the conjugate light source (20) used to project the segmented images to be selectively displayed/blocked.
