Patent ID: 8227148

Claim:
A hologram fabrication process wherein a volume hologram recording material is located on a side of a reflection type volume hologram master onto which copying illumination light is incident, and the copying illumination light incident onto the volume hologram recording material and light diffracted through the reflection type volume hologram master interfere together in the volume hologram recording material thereby copying the reflection type volume hologram master, characterized in that: a reflecting plate having a pattern of regular reflection zones is interleaved between said reflection type volume hologram master and said volume hologram recording material, and said copying illumination light incident onto said volume hologram recording material and regularly reflected light from the regular reflection zone of the said reflecting plate interfere together in said volume hologram recording material thereby allowing said regular reflection zone to be multi-recorded in a hologram having said reflection type volume hologram master copied in it, wherein the resultant volume hologram is a security hologram having an object image and a planar pattern formed therein, wherein said pattern comprises at least one microcharacter or security pattern.
