ABSTRACT:
A method of hot rolling or extrusion of a textured-surface sheet can be used to produce a large one dimensional array of fibers; these arrays can be stacked to form the two dimensional matrix required for image transfer. Alternatively, a flat ribbon can be rolled or extruded and the fiber array formed from it by altering the refractive index of alternate strips using diffusion ion exchange or implantation methods.
