Paper Abstract

Our paper deals with advanced approaches exploiting electron-beam lithography origination technologies in order to produce the so-called DOVIDs offering new visual features, though based on subwavelength origination. Synthesized security elements are recorded with a resolution reaching even 2,500.000 dpi and are specially developed for the security measures of the most important state valuable documents. We shall mention some principal features, where the ultra-precise recording of diffractive elements is requested.
