Abstract: A hologram recording and reproducing apparatus including: a coherent light source; a beam splitter which splits a beam emitted from the coherent light source into a signal beam and a reference beam; a signal beam forming unit which modulates the signal beam split and directs the modulated signal beam onto a hologram recording medium; and a reference beam forming unit which directs the reference beam to be irradiated onto a location on the hologram recording medium which overlaps with a location on the hologram recording medium on which the signal beam is incident, wherein the signal beam forming unit includes: a first light guide member which transmits the signal beam split by the beam splitter; a spatial light modulator (SLM) which modulates the signal beam transmitted through the first light guide member; and a holographic Fourier transformation optical device which focuses the modulated signal beam onto the hologram recording medium.

Abstract: A high speed hologram recording apparatus and method. The hologram recording apparatus includes: a light source for emitting coherent light; a beam splitter for splitting the coherent light emitted from the light source into a signal beam and a reference beam; a signal beam transfer unit comprising an angular deflector that changes a direction of the signal beam according to time, and irradiating the signal beam onto a hologram recording medium; and a reference beam transfer unit irradiating the reference beam at a location of the hologram recording medium where the signal beam is also irradiated.
