Paper Abstract

We discuss a method for producing high quality true color reflection holograms in silver halide based on multiple wavelength recording in a sandwiched emulsion layer. From a consideration of the literature on color theory and an experiment conducted in psychophysics, we determined optimum available laser wavelengths for color holography: 458 nm blue, 528 nm green and 647 nm red (a combination not used in the past). We then used these wavelengths to record true-color white light reflection display holograms of a set of Munsel colored papers. Ilford SP672T and SP673T emulsions provided the high spatial frequency response necessary for blue recordings. The hologram and object were measured and compared using a spot spectro-radiometer to determine the fidelity of color reproduction. The techniques were then used to record holograms of a three dimensional colored object.
