Abstract
An apparatus for recording holograms on an optical medium, in particular on an optically addressable spatial light modulation device is disclosed. For this purpose, the apparatus comprises an illumination device for emitting light, an optical medium, an image source having at least one modulation element, and an arrangement of microlenses. In this case, the arrangement of microlenses is arranged at a distance from the optical medium in such a way that the image focal points of the microlenses lie on the optical medium, such that the hologram can be generated on the optical medium.
