Abstract
A method for making an optical layer including, a first pattern projected onto a radiation sensitive surface having a first charge. Radiant energy is used to locally change the surface charge, thereby producing local areas having a second charge. The surface is exposed to an optical media having a charge that attracts the optical media to the surface. A substrate (123) with an associated charge is passed in proximity to the surface having the optical media attached. The optical media detaches from the surface and is deposited onto the substrate. The substrate (124) is heated, thereby fusing the optical media to make an optical layer (202).
