Dai Nippon Printing Co., Ltd. (DNP, Tokyo, Japan) has succeeded in recording Lippmann holograms with an image of Computer-Generated Holograms (CGHs). As Lippmann holograms are usually made by real three-dimensional object, design variation of the objects are restricted by the possibility of manufacturing the object. On the other hand, as CGHs are made by computer graphics (CG), many different kinds of virtual images can be built into holographic images. Also, it has very fine resolution because it is made by the Electron-Beam lithography system. By incorporating the image expression of the CGH into Lippmann hologram, we have developed a new hologram combining both CGHs and the Lippmann holograms.
