摘要: In this study we present an extended investigation made on holographic polymer dispersed liquid crystals. A spectroscopic of the photosensitive mixtures during polymerization and phase separation process was performed, optical characterization recorded gratings carried out using two alternative methods. The behavior diffraction efficiency transmission versus time, angle incidence, wavelength experimentally determined, results were successfully analyzed available theories for anisotropic gratings. Finally, electro-optical properties concerning beam deflection response times measured.
