HOLOGRAPHIC REPRODUCING APPARATUS AND METHOD, HOLOGRAPHIC IMPLEMENTING DEVICE AND METHOD
摘要:
A holographic reproducing apparatus includes: a photorefractive crystal configured to have holographic images recorded in a plurality of different angles respectively; and a light source configured to supply a plurality of reproducing light beams to be incident to the photorefractive crystal in different angles, wherein the reproducing light beams have a same frequency and a same optical length as a reference light beam used when the holographic images are formed. In the holographic reproducing apparatus, each of the holographic images can be presented in different angles without interference therebetween, so that observers in a plurality of orientations can view the holographic images recorded in the photorefractive crystal, thus the problem that the viewing angle is unique in the holographic reproducing procedure is addressed.
