Single layer image projection film
First Claim
1. A single layer image projection system for projecting one or more images that comprises an arrangement of optionally reflective arcuate elements having an upper arcuate surface, a lower surface, and an arcuate area bounded by the upper arcuate and lower surfaces, and an optionally reflective pattern of image relief microstructures disposed on or within at least some of the upper arcuate surfaces of the arcuate elements, wherein the arrangement of optionally reflective arcuate elements and the optionally reflective pattern of image relief microstructures are in a single layer and interact to project one or more images,wherein for an upper arcuate surface with convex surface curvature, the image relief microstructures extend downwardly from this surface terminating within the arcuate area, andwherein for an upper arcuate surface with concave surface curvature, the image relief microstructures extend upwardly from this surface terminating within an area defined by the curvature of the upper arcuate surface.

Abstract
A single layer image projection system that is made up of an arrangement of optionally reflective arcuate elements having an upper arcuate surface, a lower surface, and an arcuate area bounded by the upper arcuate and lower surfaces, and an optionally reflective pattern of image relief microstructures disposed on or within at least some of the upper arcuate surfaces of the arcuate elements, is provided. The arrangement of optionally reflective arcuate elements and the optionally reflective pattern of image relief microstructures are in a single layer and interact to project one or more images. For an upper arcuate surface with convex surface curvature, the image relief microstructures extend downwardly from this surface terminating within the arcuate area, and for an upper arcuate surface with concave surface curvature, the image relief microstructures extend upwardly from this surface terminating within an area defined by the curvature of the upper arcuate surface. Transmission of light through the system, reflection of light from the system or a combination thereof forms one or more images.
