Abstract

Our paper deals with the recent advances in synthetically written optical security devices (DOVIDs) and holograms. The synthesized holographic security elements are recorded with a resolution reaching 500.000 dpi and are specially developed for the "layman-level" security of the most important state valuables and documents, like banknotes and identity cards. We especially pay an attention to such holographic features being impossible to originate through conventional optical holography of matrix based devices.
