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