Abstract

In this work we expose the results obtained with a wide variety of phase holographic recording materials that we have characterized in the range of low spatial frequencies (≤ 32 lines/millimeter). We have considered bleached photographic emulsion, silver halide sensitized gelatin and dichromated gelatin. This low spatial frequency characterization is necessary in order to generate optimum computer-generated holograms on these materials by means of a low cost technique. In this work, we have generated correlation filters for optical pattern recognition. The experimental results confirm that the correlation filters generated on all the phase materials exhibit a good performance.
