Paper Abstract

Multicolor display holography has been described by using some different techniques. Those that allow white-light viewing of the final hologram generally involve several stages, some requiring accurate registration. The recording technique, the recording material and the processing are all important parts of the final color hologram. Various special techniques allow the production of holograms exhibiting different colors. Color control for reflection holograms usually implies the preswelling of the emulsion before the recording. In this paper we will describe different methods of obtaining different colors for reflection holography on silver halide photographic emulsion by means of chemical methods, other than the preswelling. By using a He-Ne laser at 632.8 nm for the recording, we can achieve a range of reconstruction wavelength from 550 nm to 700 nm by using different developments and bleachings as well as different temperatures during the processing. By measuring the coordinates of each point recorded, we will find its right wavelength. Thus, comparing them to those of the CIE diagram, we will know the exact location of each color in the horseshoe shape. This will allow us to choose the desired color and repeat it in the conditions previously experimented.
