Electron beam origination technology is an effective method for production of originals of nano-optical elements. E-beam lithography provides with a wide range of security features both for visual and instrumental control of authenticity of optical elements. An example of security features for visual control is SmartGlint effect, which forms a full and wide ranging parallax movement of symbols. Another example is computer generated 3D hologram with full parallax. The calculation of the hologram structure is done in Fresnel approach. The real optical element created shows high efficiency of the proposed solutions.
