Comparison of diffuse-object holograms and holographic gratings stored on acrylamide photopolymers
Abstract:In this study the diffraction efficiency of diffuse-object holograms is compared with that of holographic gratings for a constant beam ratio and different intensities in order to analyzed the storage and reconstruction process with the same wavelength. When we work with the same wavelength in the register and reconstruction process, the refraction index modulation decreases. The material used is a photopolymer based on acrylamides, consisting of acrylamide as monomer, yellowish eosin as sensitizer and triethanolamine as radical generator, all on a matrix of polyvinyl alcohol.
