The new material is formed by a sugar, pectin and vanillin dissolution. The diffraction efficiency parameter increases in comparison with only the sugar matrix, obtaining already of 10%.

We made a sugar solution (sugar in water) and it is irradiated with ultraviolet light, since the maximum absorption spectra is localized at UV region, to wavelength 200 nm. This step also corresponds to sugar photopolymer process. It is recorded applying conventional lithography technique and measures the

The photo-oxidation was carried out by changing the concentrations of ammonium dichromate. We making the analysis of the behavior of the parameters of the diffraction efficiencies through holographic gratings built with each of the saccharides mentioned.

The information in the mask is transferred to the material by temperature gradients generated by exposition to the heat. The refraction index is transformed at each material point by the temperature changes, thus the

Diffraction efficiency parameter of holographic gratings were studied in dichromated poly(vinyl alcohol) films and dichromated poly(vinyl alcohol) doped with nickel(II) chloride hexahydrate. The electrical changes of the materials were analyzed as a function of surface and volume resistivity.

In this research shown that can be used in implementing of holographic recording Films. Therefore we describe the technique how to obtain this kind of pigments trough spay drying of natural pineapple juice, which are then dissolved with water in a proportion of 0.1g to 1mL. The obtained sample is poured into glass substrates using the gravity method, after a drying of 24 hours in laboratory normal conditions the films are ready. The films are characterized by recording transmission holographic gratings (LSR 445 NL 445 nm) and measuring the diffraction efficiency holographic parameter. This recording material has good diffraction efficiency and environmental stability.
