    摘要： The invention relates to a lithograph for producing digital holograms in a storage medium (4), having a light source (6, 10) for producing a write beam (12) with a predefined beam cross section, having a writing lens (14) for focusing the write beam (12) onto the storage medium (4) to be written, the writing lens (14) being arranged in a lens holder (16), and having drive means for the two-dimensional movement of the write beam relative to the storage medium. The technical problem of writing computer-generated holograms as quickly as possible and with little effort by means of optical lithography is solved in that a first drive device (18) is provided for moving the lens holder (16) substantially at right angles to the write beam (12) and in that the aperture of the writing lens (14) is smaller than the beam cross section of the write beam (12).The inventon also relates to a method for the lithographic production of a hologram in a storage medium.

    摘要： The present invention relates to a method of producing digital holograms in a storage medium, in which the technical problem of writing computer-generated holograms by means of optical lithography as quickly as possible and with little effort with simultaneous accurate control of the timed triggering and the positioning of the write beam is achieved in that a write beam is focused onto the storage medium and moved one-dimensionally relative to the storage medium, in that a scanning beam is focused onto a trigger mask having a plurality of trigger lines and moved one-dimensionally transversely relative to the trigger lines, the movement of the scanning beam being coupled with the movement of the write beam, in that, during the scanning of the trigger lines, a timed trigger signal is generated as a function of the arrangement of the trigger lines, in that, with the aid of the timed trigger signal, the intensity of the write beam on the storage medium is controlled, and in that the hologram is written line by line by introducing radiation energy point by point, the storage medium being displaced transversely with respect to the scanning direction of the lines by a predefined distance to write adjacent lines of the hologram.The technical problem is also solved by a lithograph for producing digital holograms.

    摘要： The invention relates to a method for identifying articles, wherein article identification data are made available and the article is provided with a hologram representing said data so that the article can be identified by way of an intensity profile corresponding to said hologram. To this end, article-identifying individual data are provided, a hologram profile is digitally calculated using said individual data, and an intensity modulation of the hologram-producing beam is determined. The hologram-producing beam transfers the hologram pixels onto a hologram support that is associated with the article to be identified so that the article can be identified by way of the intensity profile reproduced from the associated hologram support.

    摘要： A holographic data storage medium has a polymer film which is set up as a storage layer whose refractive index can be changed locally by heating. The polymer film is set up for the storage of optical phase information via the local optical path length of the polymer film, which is illuminated in transmission when the information is read out. To the polymer film, there can be assigned an absorber dye, in order to at least partly absorb a write beam to input information and to give up the heat produced in the process at least partly locally to the polymer film. Preferably, a reflective layer is arranged behind the polymer film.
