Abstract
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.
