摘要

The safety system (01) is based on optical identification of highly specific, spatially appearing microstructures in a substrate by a micro-optical enlargement system integrated into the substrate. The micro-optical enlargement system (05) has an optical axis. The microstructure is formed directly from spatially formed surface at an individual micro or nano-particle (02), and is embedded in a transparent imbedding medium (03) on the optical axis of the micro-optical enlargement system.
