Color reproduction by multicolor holograms with white-light reconstruction.

Multicolor holograms for white-light reconstruction are recorded using four primary wavelengths of a krypton ion laser and a helium-neon laser. On the basis of colorimetry performed with the aid of a color computer, the colors observed with the eye through the holograms, as well as those of original transparencies (color patches), are represented as the points on a chromaticity diagram.
