ABSTRACT:
Two panels, each having a plurality of electrically-addressable, parallel light valve strips are arranged along an optical axis between entrance, exit and intermediate polarizing means. The strips of the respective panels are generally perpendicular and the entrance and exit polarizing means have their directions of polarization mutually aligned and perpendicular to the intermediate polarizing means. By sequentially activating the strips of a first panel and imagewise addressing the strips of the other panel during each such sequential activation an area image is formed.
