Abstract

L'invention concerne la constitution d'éléments de sécurité à effet optique de diffraction, et un dispositif utilisé pour le contrôle de tels éléments. L'utilisation d'hologrammes et d'autres éléments de sécurité à effet optique de diffraction pour la protection de documents et d'autres papiers de valeur, ainsi que des billets de banque contre des falsifications doit être actuellement de plus en plus fréquente. L'élément à effet de diffraction optique comporte, selon l'invention, une couche de métallisation discontinue et/ou des couches métalliques partielles et/ou des zones de couches métalliques dans différents plans, qui représentent un codage électrique, conforme à l'objectif, d'informations. Le dispositif comporte un explorateur à fonctionnement capacitif. Cet explorateur est constitué d'une pluralité d'électrodes d'émission placées les unes à côté des autres et d'une électrode de réception s'étendant parallèlement à cet agencement d'électrodes d'émission.
