摘要：

The present invention provides a holographic storage apparatus comprising a polarizing beam splitter configured to split an incoming beam into an object beam and a reference beam; a first spatial light modulator configured to modulate the object beam with an array of data; a second spatial light modulator configured to phase modulate the reference beam with an orthogonal phase function; a holographic medium configured to record an interference pattern between the modulated object beam and the modulated reference beam; a first image sensor configured to read an image of the modulated object beam; and a second image sensor configured to read an image of the modulated reference beam.
