Abstract

It has been a long and elusive goal of display holographers to produce true multicolored images closely matched to that of the object. Much progress has been reported ecently by K. Bazargan1-'' T. Kubota2 P . M. Hubel and A. A. Ward '' and H. Owen and A. E . Hurst (6) However most of the works reported require sandwiches of different materials independently exposed. Herein we wish to report our recent work in " true color" holography using single lements of silver halide dichromated gelatin as propose by J. Blythe and the Du Pont photopolymer material. Also new sandwich combinations are reported. 2. HEURISTIC DEFINITION OF " TRUE" COLOR" Since laser light is required to record holograms the reconstructed image by an incandescent source will never recreate precisely the image of a multicolored object as it appears under natural lighting. At least two major factors contribute to this problem: the object may fluoresce and the reconstruction bandwidth will always be wider than laser lines causing color desaturation. Furthermore because color perception is subjective there cannot ever be complete agreement among different observers as to the " truthfulness" of the reconstructed image. We offer the following heuristic definition which is amenable to scientific verification: A hologram is said to have " true color" if it recreates an image which has the same combination of wavelengths and their relative intensities as those
