    Abstract: An electrically alterable apparatus and method of operation thereof that permits the optical processing of an image is disclosed. The apparatus includes an array of optical cells comprised of a plurality of XY stripline arrays and a stripedomain film element. The stripe-domain wall separation and wall orientation at each point in the film element are selectively controllable for generating in the optical cell array an electrically alterable hologram. Domain wall configurations to perform various optical processing tasks are disclosed.
