Holographic storage system for reading a hologram stored on a holographic storage medium and a method carried out with the same

摘要

A holographic storage system (1) for reading a hologram (7) stored on a medium holographic dealmacenamiento (6), said system (1) comprising: holding means storage medium disposed along an optical path of a beam dereference (3); a spatial light modulator (SLM) (4) arranged along said optical path for encoding a dereference beam (3) with a code pattern (15); a detector (5) for detecting a reconstructed hologram image (7); and servo control unit (14) for determining a misalignment of said reference beam (3) and dichomedio storage (6) about the detected image and for acting upon said SLM (4) paradesplazar said code pattern (15), wherein said reference beam (3) is transmitted through said SLM (4).
