Document Type and Number:
Japanese Patent JP2009258663
Kind Code:
A
Abstract:
To provide a device for recording holograms on an optical medium, in particular on an optically addressable spatial light modulation device.
A device (1) comprises an illumination device (3) for emitting light, an optical medium (2), an image source (6) having at least one modulation element (7), and a configuration (10) of microlenses. In this case, the configuration (10) of microlenses is arranged at a distance from the optical medium (2) in such a way that the image focal points of microlenses (10', 10'a, 10'b, and 10'c) lie on the optical medium (2), such that a hologram can be generated on the optical medium (2).
