Patent number: 10800201Abstract: A security object has a document body. A lens array is formed on a top side and first information is stored in the document body. The optical detectability of the first information through the lens array is dependent on a detection direction. The document body has a top view section, in which the document body has a material layer that is translucent or opaque, and adjacent thereto a window section, in which the document body is formed of a material transparent in volume between a top side and a bottom side. The lens array extends over part of the window section and over part of the top view section and spans a section boundary between the sections. The first information also is formed partially in the top view section and partially in the window section and, in the window section, laser-marked, static second information is stored in the document body.Type: GrantFiled: March 3, 2017Date of Patent: October 13, 2020Assignees: Bundesdruckerei GmbH, Bundesrepublik Deutschland, vertreten durch das Bundesministerium des Innern, vertreten durch das BundeskriminalamtInventors: Simone Zernicek, Andreas Bosien, Michael Knebel, Andre Leopold, Uwe Seidel, Ulrich Schneider

Patent number: 8760742Abstract: A method and a device produce an individualized hologram from a generated light beam. According to the method, the light beam is individually modulated in a spatial light modulator, a holographic recording material is arranged relative to a holographic master, and the individually modulated light beam is guided in such a manner that at least part of the individually modulated light beam is refracted and/or reflected on the holographic master and an interference pattern representing the individualized hologram is produced in the holographic recording material. The individually modulated light beam is displaced relative to the holographic recording material and the holographic master to scan the entire holographic master. The recording material is arranged so as to rest on a cylindrical drum or a cylindrical drum segment and the drum is rotated about a drum axis of the drum or the drum segment during scanning of the holographic master.Type: GrantFiled: September 3, 2008Date of Patent: June 24, 2014Assignee: Bundesdruckerei GmbHInventors: André Leopold, Christian Kunath, Jens Ehreke, Gerhard Hochenbleicher, Christian Klepzig, Michael Langgassner

Patent number: 8736933Abstract: A method produces colored individualized holograms for use as security elements for documents, and to a device for producing individualized holograms. The method generates light formed of different colors, spatially modulates the light, color by color, in an individual manner, optically guides the modulated light such that the light is at least partially refracted and/or reflected on a holographic master and is superposed in a holographic recording material with the modulated non-refracted and/or reflected light, and records the hologram. The light is modulated, color by color and at the same time, by a plurality of spatial light modulators. Every color is associated with its own spatial light modulator and a plurality of monochrome modulated light beams of the plurality of colors is combined in a collinear manner prior to refraction and/or reflection on the holographic master and the superposition in the recording material to give a multicolor exposure light beam.Type: GrantFiled: September 3, 2008Date of Patent: May 27, 2014Assignee: Bundesdruckerei GmbHInventors: André Leopold, Christian Kunath, Jens Ehreke, Gerhard Hochenbleicher, Christian Klepzig, Michael Langgassner
