Abstract

The holographic build-up and erasure times of the azo-dye Disperse Red 13 in PMMA have been measured. The measurements have been taken at different reference-to-object beam intensity ratios to determine the optimum ratio for maximum diffraction of the readout beam by the photoinduced grating. These investigations have been carried out on azo-dye doped polymer films to determine their suitability for use in information processing by holographic methods. The edge- enhancement of various objects, both simple and complex, was demonstrated with this azo-dye doped polymer film, illustrating the possibility of nonlinear optical filtering using such photoanisotropic materials. The described method uses two interacting beams without any additional devices and allows the edge enhancement of moving objects.
