"The technical solution concerns an optical diffractive element for application in protection of originality of documents and various products which uses a waveguide effect. The element consists of an incoupling structure, a waveguide layer, and an outcoupling part. When the incoupling structure is illuminated, the light is guided in the waveguide layer and outcoupled by the outcoupling element. The hidden information is stored in a form of shape of the outcoupling element or in its microstructure. All parts of the system can be easily integrated in commonly used holographic security elements while the holographic foil can be used as a waveguide layer."@en . "\u0160kere\u0148, Marek" .
