Abstract
The invention relates to a method for reading-out data recorded in a holographic medium (106) as a phase-modulated pattern of data pixels. The method comprises the steps of reconstructing said phase-modulated pattern (P), duplicating said reconstructed phase- modulated pattern in a first reconstructed phase-modulated pattern (Pl) and a second phase- modulated pattern (P2) shifted from said first reconstructed phase-modulated pattern by an integer number of data pixels, and having interfere said first and second reconstructed phase- modulated patterns.
