Recording and Demonstration of Cultural Assets by Color Holography (II)

Recording Method of Hologram for Optimizing the Color Reproduction

Abstract

One of the most important application of color holography is to record cultural assets and to demonstrate them by holograms. For this purpose, the discussion of the methods for recording the color hologram is necessiated together with analysis of the color reproduction.
In this paper, the Lippmann color hologram using a holographic stereogram is presented for the second report of the study on the application of color holography to recording and demonstration of the cultural assets. This method is considered as the promissing method to realize the optimum color reproduction discussed in the first report of this study. The color hologram is recorded with only one wavelength by using the technique of pseudo-color hologram. The reconstructed wavelengths for the three primaries can be chosen freely by controlling the thickness of the photographic emulsion properly in the recording stage. The perspective images for holographic stereogram are obtained photographically, so the restriction for the object to be recorded is removed. The color hologram having these features are suitable for the application mentioned above.
