Paper Abstract

We review the properties and relative usefulness of 3 non silver Volume holographic recording materials that are available today. Dichromated Gelatin (DCG) will receive the most attention followed by Dupont Omnidex products and a light treatment of Polyvinyl Carbazole (PVK). Enhancement and control of color, bandwidth and diffraction efficiency of volume reflection holograms recorded in DCG and photopolymers is discussed. Methods of increasing the bandwidth while shifting the center frequency toward the red is given for photopolymers. Red pseudo color will be covered thoroughly so that the practitioner will have all the elementary tools to make full color and broadband DCG holograms from scratch. The entire DCG technology is disclosed as it relates to production of high quality display holograms that span the spectrum and may be narrowband and very deep or shallow and broadband.
