Single-layer image projection system, sheet material, document, consumer or non-consumer product and large-image projection product

摘要

It is a single layer image projection system which is comprised of an optionally reflective arched element arrangement having an upper arched surface, a lower surface and an arched area joined by the arched upper and lower surfaces, and an optionally standard reflective image relief microstructures arranged on or within at least part of the upper arcuate surfaces of the arcuate elements. the arrangement of optionally reflective arched 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 arched surface with convex surface curvature, the image relief microstructures extend downwardly from that surface, ending within the arcuate area, and for an upper arched surface with concave surface curvature, the relief microstructures image extend upwards from that surface, ending within an area defined by the curvature of the upper arched surface. light transmission through the system, light reflection from the system or a combination thereof forms one or more images.
