Abstract

For applications involving the transmission of optical data through media such as air or water, a dynamic correction scheme must be employed. Many image restoration experiments using photorefractive polymeric composites have been described in literature, although the previously available materials resulted in the use of impractical experimental geometries. We have focused our attention on the formulation and characterization of high-performance photorefractive composites based on N,N'-Bis(3- methylphenyl)-N,N'-bis(phenyl)benzidine. The experiment has been modified to distinguish between sender and receiver locations, so a clean reference beam is required at the receiver. We demonstrate the ability of our group’s composite to function in the practical geometry. The proposed geometry is a combination of two-beamcoupling and four-wave-mixing layouts, and the data indicating the efficiency of the composite in the geometry without scattering of optical radiation is presented. The effect of rotating the polarization of the object beam relative to p-polarization has also been quantified.
