Abstract
A photorefractive polymer based on poly(N-vinylcarbazole) photoconductive p olymer was improved by use of plasticizer mixture of N-ethylcrbazole and 1, 3-biscarbazolylpropane. The modified photorefractive polymer was applied to the nonlinear materials for a matched-filter four-wave-mixing optical corr elator. The operation of image correlation was demonstrated with the 10:1 o f signal-to-noise ratio.
