Title (EN) ENHANCED SECURITY OF OPTICAL ARTICLE
(FR) SÉCURITÉ AMÉLIORÉE D’ARTICLE OPTIQUE
Abstract: front page image
(EN)An optical article comprising a mark disposed on the optical article; wherein the mark comprises an optical state change material; wherein the optical state change material undergoes a change in its optical state when exposed to an activation signal selected from one or more of a laser, thermal energy, infrared rays, X-rays, gamma rays, microwaves, visible light, ultraviolet light, ultrasound waves, radio frequency waves, electrical energy, chemical energy, magnetic energy, and mechanical energy; wherein the optical article is transformed from a pre-activated state to an activated state when an authorized activation method is used; and wherein the optical article is transformed from a pre-activated state to an incorrectly activated state when an unauthorized activation method is used. A method and a system for changing the functionality of the optical article are also provided.
(FR)Un article optique comprend une marque disposée sur l’article optique; la marque comprenant un matériau changeant d’état optique. Le matériau changeant d’état optique subit un changement de son état optique lorsqu’il est exposé à un signal d’activation sélectionné parmi un ou plusieurs des éléments suivants : laser, énergie thermique, rayons infrarouges, rayons X, rayons gamma, micro-ondes, lumière visible, lumière ultraviolette, ondes ultrasoniques, ondes radioélectriques, énergie électrique, énergie chimique, énergie magnétique et énergie mécanique; L’article optique est transformé d’un état pré-activé en un état activé lorsque l’on utilise un procédé d’activation autorisé et l’article optique est transformé d’un état pré-activé en un état incorrectement activé lorsque l’on utilise un procédé d’activation non autorisé. L’invention concerne également un procédé et un système permettant de changer la fonctionnalité de l’article optique.
