Photopolymers in optical computing: materials and devices

The applications of Dyed Gelatin and Polyvinyl alcohol for non-Fourier image processing are described. Examples of contrast reversal, edge enhancement, character recognition and addition and subtraction of images using Dyed gelatin films are presented. Dyed Polyvinyl alcohol has been used in a Optical Correlator for the detection of Cross Correlation peak which can serve as an input for a neural network.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
