  • AZIMUTHALLY MODULATED SCATTERING DEVICE
    Publication number: 20210173130
    Abstract: Optical elements with anisotropic, patterned surface relief microstructures in which information is encoded in the distribution of the orientation of different zones. From the analysis of the distribution of the light scattered from the element, the orientation distribution in the element and therefore the encoded information can be evaluated. The elements are particularly useful for securing documents and articles against counterfeiting and falsification.

  • METHOD FOR GENERATING ALIGNMENT ON TOP OF A LIQUID CRYSTAL POLYMER MATERIAL
    Publication number: 20190162889
    Abstract: The present invention relates to a method for manufacturing an optical element including a layer comprising anisotropic optical function and alignment capability. The layer is formed from a composition comprising polymerizable liquid crystals and one or more photo-orientable substances. Alignment on top of the layer is achieved by exposure to linearly polarized light.
