Holographic multiplexing using photoinduced anisotropy and surface relief in azopolymer films

Abstract

The properties of gratings in an azobenzene polymer inscribed with different combinations of the polarizations of the recording beams are investigated and the optimal conditions for polarization multiplexing are found. Two holograms are stored with the same spatial frequency and the same polarization of the reference beam, varying the polarization of the subject beam. Simultaneous and separate read-out of the reconstructed images is demonstrated.
