Hologram recording medium, hologram recording/reconstructing apparatus, and hologram recording/reconstructing method

摘要

A hologram recording medium comprises a hologram recording layer for recording a hologram, and a wedge substrate for varying the propagating direction of a reference light and an object light incident upon the hologram recording medium. By rotating the hologram recording medium comprising the hologram recording layer and the wedge substrate, the propagating direction of the reference light and the object light are varied, whereby angle multiplex recording of holograms can be realized with ease.
