Kind Code:
A
Abstract:
The invention relates to an optical holographic device for reading out a data page recorded in a holographic medium ( 106 ). The device comprises means ( 104, 105 ) for forming an imaged data page from the data page. The imaged data page comprises imaged data bits (a, b, c, d) having a first size (s 1 ) in a direction (D). The device comprises means for detecting ( 114 ) the imaged data page. The detecting means comprise detector elements having a second size (s 2 ) in the direction (D). The second size is larger than the first size. The device comprises displacement means ( 200 ) for displacing the imaged data page in the direction (D) with respect to the detecting means so as to scan the imaged data page.
