Holographic storage system using destructive interference for pixel detection

摘要

The present invention relates to a holographic storage system (1), and more specifically to a method for pixel detection in a coaxial holographic storage system. In a holographic storage system (1) according to the invention, with a coaxial arrangement of an object beam (3) and a reference beam (2) the bright pixels within the object beam (3) have a phase shift of essentially À relative to the reference beam (2). For readout of a data page contained in a reconstructed object beam (10) a detector (11) detects an interference pattern generated by the interference between the reference beam (2) and the reconstructed object beam (10).
