    摘要: The present invention relates to 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 according to the invention and therefore the encoded information can be evaluated. The elements according to the invention are particularly useful for securing documents and articles against counterfeiting and falsification.
