20120162731 | AUTHENTICATION HOLOGRAM, AND ITS FABRICATION PROCESS - The invention provides an authentication hologram using a Lippmann hologram that enables a 3D object image having a vertical and horizontal field of vision as well as planar, added information viewable at a specific angle alone are viewable, as shown in FIG. | 06-28-2012 |
20120194887 | HOLOGRAM FABRICATION PROCESS AND FABRICATED HOLOGRAM - A volume hologram recording material is located on the side of a reflection type volume hologram master onto which copying illumination light is incident, and the copying illumination light incident onto the recording material and light diffracted through the master interfere together in the volume hologram recording material thereby copying the reflection type volume hologram master. In this case, a reflecting plate having a fine regular reflection pattern is interleaved between the master and the recording material, and the copying illumination light incident onto the recording material and regularly reflected light from the reflecting plate having the regular reflection pattern interfere together in the recording material thereby allowing the regular reflection pattern to be multi-recorded in a hologram having the reflection type volume hologram master copied in it. | 08-02-2012 |

20090219592 | FABRICATION PROCESS FOR CHOLESTERIC LIQUID CRYSTAL MEDIA HAVING A VOLUME HOLOGRAM - The invention provides a process capable of fabricating a cholesteric liquid crystal medium having a volume hologram with efficiency yet without recourse to complicated steps such as an alignment step. This is achievable as follows. A volume hologram layer is formed on a substrate, and a cholesteric liquid crystal layer is then formed on another substrate comprising a center substrate film that is subjected to bondable treatment. The volume hologram layer is applied to the center substrate film that is subjected to bondable treatment, and placed in a state where the volume hologram layer and cholesteric liquid crystal layer are laminated together via the substrate. The substrate is peeled off the volume hologram layer, and an adhesive layer is formed on the surface of the volume hologram layer off which the substrate is peeled off, followed by the provision of the substrate on the adhesive layer. Finally, the multilayer structure is shaped into a label form of cholesteric liquid crystal medium having a volume hologram layer. | 09-03-2009 |
