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.
