Don't know if this 1974 paper is freely downloadable or not.

Highly Reproducible Hologram of Hardened Dichromated Gelatin Processed with HCl

(Received June 7, 1974)

Processing of hardened dichromated gelatin (HDG) developed by Shankoff, Lin and others are improved by adding a treatment with HCl aqueous solution. The diffraction efficiency of a HCl-processed hologram is as high as that of the previous HDG holograms. The HCl processing yields the light sensitivity ten times greater than that obtained by the previous method, and a wide saturation range of the diffraction efficiency in a HDG hologram. By recording Fourier transform holograms in this saturation region, the nonuniformity of diffraction efficiency can be reduced by one-third when combined with a 2 cell/bit information recording configuration. A mechanism of the saturation characteristics is discussed in detail based on optical visibility.
