Abstract

1.- Método para marcar e identificar o autenticar un elemento, que comprende los pasos de: proveer al elemento de una marca que contiene partículas distribuidas en forma aleatoria, registrar y almacenar datos representativos de dicha distribución aleatoria usando un dispositivo de lectura que comprende medios de iluminación y medios de detección óptica, e identificar o autenticar el elemento marcado mediante la posterior lectura de los datos representativos de dicha distribución aleatoria y su comparación con dichos datos almacenados, CARACTERIZADO porque las partículas distribuidas en forma aleatoria consisten en escamas de polímero de cristal líquido colestérico que reflejan un componente de luz polarizada circular, y el mencionado dispositivo de lectura explota la polarización circular para discriminar las escamas del fondo porque forma una imagen de diferencia de polarización circular. 2.- Método de acuerdo a la reivindicación 1, CARACTERIZADO porque dicha imagen de diferencia de polarización circular es formada entre dos imágenes obtenidas bajo dos condiciones de polarización diferente seleccionada desde el grupo de no polarizado, polarizado circular izquierdo, y polarizado circular derecho.3.- Método de acuerdo con las reivindicaciones 1 o 2, CARACTERIZADO porque dicha escama de CLCP tiene por lo menos una banda de reflejo espectral en por lo menos uno del espectro electromagnético ultravioleta, visible, e infra-rojo. 4.- Método de acuerdo con la reivindicación 3, CARACTERIZADO porque dicha escama de CLCP tiene por lo menos dos bandas de reflejo espectral en por lo menos uno del espectro electromagnético ultravioleta, visible, e infra-rojo. 5.- Método de acuerdo con la reivindicación 4, CARACTERIZADO porque cada banda de reflejo espectral está polarizada en forma individual en forma circular de mano izquierda o de mano derecha.
