PHASE-ENCODED MULTIPLEXING METHOD AND APPARATUS USING COMPLEX PHASE CODE IN HOLOGRAPHIC MEMORY SYSTEM

摘要

The present invention relates to a method for multiplexing phase code in holographic memory system, comprising the steps of outputting a complex phase code through complex phase code algorithm, whereby the complex phase code is used for an address beam when a phase is multiplexed-; modulating a phase of the address beam through a phase-type spatial light modulator; modulating amplitude of an object beam through signal amplification-type spatial light modulator; and interfering the amplitude-modulated object beam with the phase-modulated address beam using a photo refraction medium.
