Abstract

The sugar cane crystals (sucrose) are used as matrix to obtain computer holograms. 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 parameter of diffraction efficiency. With the purpose to reduce the exposition time at UV radiation of this emulsion, we made studies with artificial organic colorant with azo components.
