RESEARCH UPON TRANSFER DUPLICATION OF RELIEF HOLOGRAMS
浮雕全息图的转印复制技术研究

This paper presents the application of optical epoxy resin as transfer medium to duplicatethe relief hologram onto the hard base material. Experiments have been conducted on photo sensitiveand thermal sensitive resins in relief hologram duplication. The results have shown that thediffractive efficiency and spatial frequency of the duplicated hologram are approximate to those of theorigiral ones, and its environmental stability is satisfactory. The new one-time transfer duplicatingtechnique,its simple process and low investment offer a practical value in mass - duplicatingproduction.
