Color evaluation of full color hologram

This paper concerns the new full color mastering process in order to obtain full color three-dimensional Lippmann holograms with flipping effect. As holographic recording materials, both newly developed red-sensitized silver halide P7000 and photopolymer were appropriated. In this study, the color reproduction and the viewable zone in vertical and horizontal directions of resulting full color Lippmann holograms were examined. The angle dependence of the reproduced colors of the holograms with both the new H1H2 mastering method and the previously reported modified Denisyuk mastering method were evaluated. The holograms using the new method showed better color reproduction and were brighter than the holograms using the modified Denisyuk method. To combine above mastering technology with mass-production technology and layer structure technology, we have succeeded in the mass-production of full color holograms with flipping effect.
