Abstract

A találmány tárgya alkalmazás és eljárás dokumentumok vizsgálatára. Afényelhajlási jelenséget hasznosító biztonsági elemekkel, különösenhologramokkal ellátott dokumentumokat jelenleg költséges optikaivizsgálóberendezések segítségével ellenőrzik. A teljes ellenőrzésifolyamat olyan hosszú ideig tart, hogy ez a vizsgálati módszer nagysebességű dokumentumfeldolgozó berendezésekben való alkalmazásra nemalkalmas. A fényelhajlás jelenségét hasznosító biztonsági elemekbőlkialakított eredetiségjegyek alkalmazásánál fokozza a biztonságot, haezek vizsgálatát gyorsan lehet végrehajtani. A fényelhajlás jelenségéthasznosító biztonsági réteg szakaszos fémrétegből és/vagy részbenfémes rétegekből, és/vagy különböző síkokban kialakított fémes rétegekzónáiból van kialakítva. A villamos vezetőképesség meghatározásáraismeretesek különféle mérési eljárások. A gyakorlatban az érintkezésnélkül, kapacitív úton történő mérés bizonyult praktikusnak. ÓThe subject of the invention is an application and method for examining documents. Documents equipped with security elements utilizing the phenomenon of light bending, especially holograms, are currently checked with the help of expensive optical inspection equipment. The entire inspection process takes so long that this inspection method is unsuitable for use in high-speed document processing equipment. The use of authenticity marks made of security elements that utilize the phenomenon of light diffraction increases security, and the examination of these can be carried out quickly. The safety layer utilizing the phenomenon of light diffraction is formed from a discontinuous metal layer and/or partially metallic layers and/or metallic layer zones formed in different planes. Various measuring procedures are known to determine electrical conductivity. In practice, non-contact, capacitive measurement has proven to be practical. HE
