HOLOGRAM REPLICATING METHOD AND HOLOGRAM REPLICATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve easiness in the observation of different images when observing an image recording medium where different images are reproduced with the movements of an eye point.

SOLUTION: In a hologram replicating method, a hologram master having a hologram image recorded thereon is arranged with respect to a surface of a hologram recording medium. First laser light is applied onto the hologram master and the hologram recording medium via a diffusion plate. Second laser light is modulated based on additional information. The modulated second laser light is applied onto the hologram recording medium via the hologram master.
