Popis:	An optical processor for direction independent differential operation a/ax + is/ay is described and feasibility studies for filter fabrication are reported. The resulting intensity distribution of the filter function can be generated by superimposing periodic time dependent pulse functions which modulate a writing beam (flying spot, monitor). Hence the filter transmission can be registered on a photographic film or by real time processing on an electro-coherent optical converter. This kind of filter generation allows changing the filter parameters with high speed, controlled by computer. The application of this processor to medical and biological images will be demonstrated.
