Holographic Microparticles OVDot

Faceted metallic particles with the size of 100-600 mcm which are randomly embedded in a substrate all over a document page. Holograms are applied over the surface of microparticles by the electron-beam lithography method and contain a nanoimage or a nanotext. Magnification mode shows how elements of a holographic image change their color at different angles of illumination and observation (fig. 1).
