Using the rainbow effect, produced by using a white light source in the reconstruction process of an image hologram, it is possible to obtain normal color two-dimensional images. The technique described in this work requires the recording of three holograms on the same plate, using laser light of a single wavelength (He-Ne laser, A = 632.8 nm) with three reference beams, each at a different angle. The color separation technique of Gale and Knop [Appl. Opt. 15(19), 2189-2198 (1976)] was used to obtain three black-and-white transparencies from one color transparency. The holographic image can be observed when the hologram is illuminated with a white light source. The experimental setup and the conditions for obtaining original color objects are discussed.
