Abstract
Azo-dye doped polymer (ADP) systems have shown to be remarkable photosensitive media for holographic recording and optical computing. The totally reversible trans-cis photoionization mechanism induced by actinic light allows the real-time recording of phase holograms on the doped polymer matrices. These ADP systems can also be used to perform polarization holography as they present the Weigert effect. Real-time operations such as contrast reversal, optical demultiplexing, addition and subtraction of two overlapping cross-polarized signals have been performed successfully.
