Holograms in colored dichromate gelatin with natural colorant

The holographic properties of dichromate gelatin (DCG) doped with natural colorants, in order to change the absorbance spectrum profile, and increasing the material sensibility, obtaining a good photo sensibility in other spectral emission line laser as blue. We showed some basics studies referent possible mechanism to storage information with this doping, and reported results. We show a light description technique to obtain holograms with these colored materials, as some experimental results.
