Abstract: An optical image processor utilizes a source of partially coherent light and a spatial filter with a highly selectable modulation transfer function for processing an image, which may be present in real time. The spatial filter contains electro-optic material with electrodes arranged on such material to form a plurality of annular bands of different radii that are concentrically-situated and invididually-addressable. The annular bands are changeable in transmissivity in a continuous spectrum from transparent to opaque in response to an electrical signal on the respective electrodes of the bands. A first optical transmission path receives the image to be processed and optically transmits the image to the spatial filter for processing. A second optical transmission path receives the image processed by the spatial filter and optically transmits the image to an output port.
