摘要： The invention relates to a method for calculating a light field which propagates between a non planar surface of a computer-generated hologram and a planar reconstruction surface, in which an intermediate plane arranged in front of the hologram is defined, in which the propagation of the light field between the reconstruction plane and the intermediate plane is calculated by means of a transformation, and in which the propagation of the light field between the non-planar hologram surface and the intermediate plane is estimated. This method solves the technical problem of taking account of the geometrical distance differences that arise on account of unevennesses of the storage medium ill the calculation of the hologram function and the reconstruction or read-out and at the same time of specifying a fast algorithm. The invention also relates to a method for producing a hologram, storage medium and a device for reading out a hologram.

摘要： The invention relates to a method for calculating a computer-generated hologram, in which the pixel distribution of the computer-generated hologram is calculated, in which the pixel distribution of a macroscopic superstructure is calculated and in which the pixel distribution of at least one computer-generated hologram is interconnected with the pixel distribution of the macroscopic superstructure to form a pixel distribution to be written in a storage medium. Similarly, the invention relates to a method for writing the hologram, a storage medium and also a reading device. Therefore, both a computer-generated hologram and a macroscopic superstructure which can contain directly readable information can be brought together in a pixel distribution.

摘要： The invention relates to a storage medium, preferably a carrier. The aim of the invention is to make manipulation of data information of the storage medium or of non-authorized copies of the storage medium visible. For this purpose, the storage medium comprises a transparent layer and a layer produced from an opaque material, the layer of the opaque material having a section with a medium transmittance between 0% and 100% which is semi-transparent to electromagnetic radiation and an informative content comprising the value of the medium transmittance being stored in the storage medium.
