摘要： An optical element where a first and a second image is at least partially encoded by a pattern of a non-periodic, anisotropic surface relief microstructure such that when light is incident on the surface of the element the first image is optimally visible under a first viewing angle and the second image is optimally visible under a second viewing angle. The optical element is particularly useful for securing documents and articles against counterfeiting and falsification.
