<title>Holographic duplicating technique using optical epoxy resin as a transfer medium</title>

Abstract

SThis paper presents the apppliation of optical epoxy resin as transfer medium to duplicate the relief hologram onto the hard base material. Experiments have been conducted on photo sensitive and thermal sensitive resins in relief hologram duplication. The results have shown that the diffraction efficiency and spatial frequency of the duplicated hologram are approximate to those of the origiral ones, and its environmental stability is satisfactory. The new one-time transfer duplicating technique , its simple process and low investment offer a practical value in massduplicating production.
