<title>Progress in true-color holography</title>

Abstract

It has been a long and elusive goal of display holographers to produce true multicolored images closely matched to that o the objects. ,21uch progress has been reported recently by K. Bazargan l , T. Kubo ", P. M. Hubel and A. A. Ward ' ' ' , and H. Owen and A. E. Hurst ". However, most of the works reported require sandwiches of different materials independently exposed. Herein we report our recent work in "true color" holography using single e],ents of silver halide, dichromated gelatin (as proposed by J . Blyth ' ) ) , and the Du Pont photopolymer material . 1 new sandwich combinations are reported.
