Abstract Three-dimensional color holographic display has important applications in visual representation of artworks, industrial products, museum items, medical images, etc., and has been always a long and diligent research goal for holographers and researchers. Through Slavich fine-grain silver-halide emulsion and Du Pont photopolymers have been successfully developed for color hologram recording, the research results of color holography based on dichromated gelatin material are still very limited. In this paper, we will summarize our recent results of color holographic display based on single-layer monochromatic and panchromatic dichromated gelatin materials. Firstly, based on the red sensitive methylene-blue sensitized DCG material, a new method is developed for the wide-range quantitative adjustment of the playback wavelength of Lippmann holograms. The main feature of this technique is homogenuously introducing a water-soluble organic reagent acrylamide into photosensitive layer as preswelling reagent and wavelegth adjuster, during the exposure process acrylamide will not react with other active reagents in DCG layer, but it will completely dissolve into water during the development process, this will result in an uniform shrink throughout the thickness of the photosensitive layer, and lead to the image reconstructed at shorter wavelength after the conventional dehydration process in isopropyl alcohol.
