ABSTRACT:
A contrast and resolution enhancing optical display screen has a plurality of straight, light-absorbing fibers embedded in at least a layer of the screen, the layer otherwise having uniform optical and physical properties. The fibers are so directed that the lines containing their axes converge toward the optical center of the first element of a lens system. Uniformity of image intensity is promoted. Sheets of material having fibers with the required arrangement are formed by: forming a thick slice having parallel fibers, bending the thick slice in a spheroidal mold or pattern at well below the working temperature until the fibers form the desired radial arrangement, and cutting the curved thick slice in at least two parallel chordal planes to form a thin sheet with fibers embedded in it. The fibers are disposed radially of a center outside the sheet.
