Title (EN) OPTICALLY ACTIVE MATERIALS AND ARTICLES AND SYSTEMS IN WHICH THEY MAY BE USED
(FR) MATÉRIAUX OPTIQUEMENT ACTIFS, ARTICLES ET SYSTÈMES DANS LESQUELS ILS PEUVENT ÊTRE UTILISÉS
Abstract:
(EN) The inventors of the present application developed novel optically active materials, methods, and articles. One embodiment of the present application is an optically active article, comprising: an infrared-reflecting material positioned adjacent to an optically active substrate such that the infrared-reflecting material forms a pattern that can be read by an infrared sensor when the optically active substrate is illuminated by an infrared light source. Another embodiment of the present application relates to a method of manufacturing an optically active article, comprising: obtaining an optically active sheeting; and positioning an infrared-reflecting material on the optically active sheeting to form a pattern. The optically active article may be, for example, a license plate.
(FR) Les inventeurs de la présente demande ont mis au point de nouveaux matériaux optiquement actifs, des procédés associés et des articles en contenant. Un mode de réalisation de la présente demande porte sur un article optiquement actif comprenant : un matériau réflecteur de rayonnement infrarouge placé à côté d'un substrat optiquement actif d'une manière telle que le matériau réflecteur de rayonnement infrarouge forme un motif qui peut être lu par un capteur infrarouge quand le substrat optiquement actif est éclairé par une source de lumière infrarouge. Un autre mode de réalisation de la présente demande concerne un procédé de fabrication d'un article optiquement actif comprenant les étapes consistant à : obtenir une feuille optiquement active ; et positionner un matériau réflecteur de rayonnement infrarouge sur la feuille optiquement active de manière à former un motif. A titre d'exemple, l'article optiquement actif peut être une plaque d'immatriculation.
