Holographic storage system based on common path interferometry

摘要

The present invention relates to a holographic storage system (20), and more specifically to a holographic storage system (20) using a phase spatial light modulator (6). According to the invention a holographic storage system (20) with a phase SLM (6) for imprinting a 2-dimensional phase data pattern onto an object beam (7) includes a common path interferometer (31, 32, 40) for converting the phase data pattern into an intensity data pattern.
