  • Patent number: 9599757
    Abstract: Tooling and optic elements for a retro-imaging system may be formed on order near atomic level of accuracy by making use of either etching or growth techniques of a cubic crystal lattice, such as silicon. The elements may be formed directly using selective etching or epitaxial growth by coating and clear resin lamination, or replicated to avoid shrinkage and curvature by use of low shrinkage resins or double-fill molding techniques. Through the use of these highly accurate reflection/diffraction elements, floating images may be formed with relatively high resolution in retro-reflective imaging systems, for example.

  • Patent number: 9588347
    Abstract: A device for generating a virtual light image. The device includes a real light source, a curved retroreflector surface, and a semi-transparent mirror. The retroreflector surface is situated so that the light of the real light source transmitted through the semi-transparent mirror does not reach the retroreflector surface. A shape of the retroreflector surface for a given visibility range, at least in a subregion of the area that is essential for the image in the visibility range, is determined by the fact that at each point of the subregion, the pair of a reflection angle A and an optical distance between this point of the subregion of the retroreflector surface and the virtual light image is Pareto-minimal, provided that the subregion of the retroreflector surface does not interrupt primary beams from the real light source to the semi-transparent mirror.
