Title:
DEVICE FOR READING OUT HOLOGRAM
Document Type and Number:
Japanese Patent JP2009258664
Kind Code:
A
Abstract:
To provide a device and method for transmissively reading out holograms from an optical medium, in particular an optically addressable spatial light modulation device.
A device 1 transmissively reads out holograms generated by writing light in an optical medium 2, in particular holograms generated in an optically addressable spatial light modulation device. For this purpose, the device 1 comprises an illumination device 3 for emitting light and an optical system 6 for directing the light from the illumination device 3 onto the optical medium 2. In this case, the optical system 6 is arranged in a beam path of the writing light.
