  • DEVICES FOR RECORDING OR READING OUT AN ENCODED HOLOGRAM
    Publication number: 20090021812
    Abstract: The invention relates devices for recording or reading out an encoded hologram. Said devices are arranged to record or to read out spatially separated data structures, as well as mutually spatially separated data holograms (36) and positioning holograms (37) associated with positioning structures that are structurally simple compared to the data structures. Said positioning holograms (37) can be analyzed separately from the data holograms (36) in order to align a modulation pattern in an iteration. The hologram can thus be correctly aligned relatively easily even in the event of complex data structures or modulation structures.
