Two and three primary colors derived from an He–Ne gas laser and an argon gas laser were employed in recording and reconstructing holograms. For the tricolor case it is possible to reconstruct a three-dimensional multicolor image which possesses almost all the natural hues of the original object. Each wavelength generates an independent fringe system that is recorded on a photographic plate with a thick emulsion that constitutes a three-dimensional recording medium. In reconstruction, each fringe system diffracts light in a manner satisfying the Bragg relation for a particular reconstructing wavelength. If the reconstruction wavelengths are the same as the original wavelengths used to record the fringe systems, the result is a multicolor reconstruction possessing few or no ghost images. In our experiments, the angle between the object beam and the reference beam was greater than 100°, and the photographic plates were oriented so that the fringe surfaces were approximately perpendicular to the emulsion surface. This minimized the deleterious effects of single-color, ghost image formation and shrinkage during development. Finally, a method of synthesizing multicolor scenes using a multiple-exposure recording with one wavelength and reconstructing with several wavelengths is described.
