Abstract (en)
[origin: WO2005057583A1] The invention relates to an optical holographic device for reading out a data page recorded in a holographic medium (106). The device comprises means for receiving the holographic medium, means for imaging the data page and means (114) for detecting the imaged data page. It also comprises, between the receiving means and the detecting means, an electro-optical system (200, 300, 400) which magnification can be changed by application of a voltage between electrodes.
