Paper Abstract
Preparation of holographic gratings using photosensitive films pectin-H2O-oxidizing agent exposed to a He-Cd laser, wavelength of 442nm. For the photo-oxidation, we used two agents: ammonium dichromate and iron ammonium citrate. Parallel studies performed experimental variation of angles between overlapping beams that generate the interference pattern, generating different spatial frequencies in the holographic gratings. Were prepared from pectin-water-ammonium dichromate and pectin-water-ammoniacal iron citrate. Results module of the transfer function (MTF) of the materials used, to determine the diffraction efficiencies as a function of the spatial frequency (line/mm) of each holographic gratings, which were prepared with different pectin and oxidizing agents. We made an experimental analysis of the MTF, comparing each of the films with different photosensitizers applied.
