Paper Abstract

New holographic materials with high resolution broaden the possibilities of applications of color holography. The color rendering of two of these materials, the Russian silver halide material PFG 03 and DuPonts photopolymer, was investigated and compared. This was done by using the CIELAB color system, taken into account luminance, hue, and chromaticity of a holographic image. Further on results in diffraction efficiency, image resolution, and signal to noise ratio are presented. Taking a good quality color hologram of cultural historic objects is often only the first step of an investigation. Measurements of the microscopic structure or the correlation of holographically stored handwritten signs is sometimes necessary. In the second part of the paper measurements are presented on holographic and coherent optical filtering of cuneiform signs. Results of measurements with originals and holograms are compared.
