A 3D Cryptographic Information Protective Holographic Element

Resumo

Protective elements formed in a 3D hologram recorded in a polymer nanocomposite, such as a lens hologram, a cryptographic information lens hologram, a hologram with a hidden cryptographic image invisible to the naked eye, and a transmissive element based on the volume hologram of the flat body, are studied. Holograms are recorded on a nanocomposite material that is a photopolymerization monomer composite containing various photosensitizers and nanoparticles.
