HOLOGRAPHIC STORING DEVICE

摘要

PURPOSE: A holographic storing device is provided to overcome limitation to recording capacity increase and enhance productivity and cut down production cost utilizing a holographic optical element. CONSTITUTION: A holographic storing device comprises a light source for generating light; alight divider for diving light into reference light and object light; a hologram memory; a first beam diffuser; a first reflective mirror; a first beam deflector; a second beam deflector; a multiple holographic element; a light interruptor; a third beam deflector; a second beam diffuser; a light modulator for displaying the object light reflected from the second reflective mirror; a lens for making the reflected object light incident to the hologram member; and a light detector for converting light information into an electric signal.
