  • Multiple image scattering device
    Patent number: 11054551
    Abstract: 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.
    Type: Grant
    Filed: April 11, 2016
    Date of Patent: July 6, 2021
    Assignee: ROLIC AG

  • Multiple hidden image security device
    Patent number: 10889141
    Abstract: The invention relates to an optical security device with multiple hidden images which become visible by arranging a polarizer above or below the device. Additional images become visible upon rotation of the polarizer. The optical device comprises two patterned optical retarders and a polarizer between the retarders.
