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