ABSTRACT:
Disclosed is a hologram recording method using a beam with a very large incident angle, a hologram reproduction apparatus using a holographic reflector, a hologram reproduction method using the same and a flat display element apparatus using a holographic reflector. The hologram recording method using a beam with a very large incident angle comprises the steps of generating a sheet beam as the reference beam, and introducing the reference beam into the recording medium at an incident angle of at least 70°. The hologram reproduction apparatus using a holographic reflector comprises a light, a holographic reflector, an adjustor, and a hologram. Also, the hologram reproduction method using the hologram reproduction apparatus comprises the steps of irradiating a beam emitted from a light source as a reference beam to a holographic reflector, reflecting the reference beam illuminated to the holographic reflector therefrom to generate a reconstructed beam, and allowing the generated reconstructed beam as a reference beam to pass through a hologram to reproduce the hologram. The flat display element apparatus comprises a light source, a holographic reflector, an adjustor, and a flat display element.
