Abstract

We have generated bidirectionnal spatial differentiation optical operators as synthetic holograms following the method of Lohmann. We use these filter holograms to perform mathematical operations: - the first and second order bidirectionnal spatial differentiation as Gradient and Laplacian operators, - the Exponential and Gaussian operators, High-pass and Low-pass filters. We have tried to apply these generated holograms to extract information from radar and aerial imaging for the enhancement and the restitution of contours of the images in the hope of improving qualitative and quantitative information. The holographic image processing can be done with extreme rapidity and is convenient when we have sets of several images to process. Furthermore we present some results in the domain of spatial light modulators able to record and read either images or convolution operators (to avoid photography).
