Abstract

Un dispositivo de seguridad comprende un substrato transparente (100) que tiene una capa opacificante (102) colocada sobre por lo menos una superficie. Una capa de rejilla reflectiva (103) comprende uno o más arreglos de acanaladuras, y una capa de material de cristal líquido (114) se coloca sobre por lo menos una porción de la capa de rejilla. Los arreglos de acanaladuras tienen un espaciado de acanaladura tal que las moléculas de cristal líquido dentro de la capa de material de cristal líquido se alinean sustancialmente para polarizar la radiación óptica que pasa a través de las mismas. El dispositivo de seguridad además incluye aberturas formadas en la capa opacificante y la capa de rejilla que comprenden un elemento óptico difractivo transmisivo (DOE). El dispositivo de seguridad de esta manera comprende una característica de seguridad transmisiva, visible cuando se visualiza en modo de transmisión a simple vista, en combinación con una característica de seguridad reflectiva, encubierta, visible únicamente utilizando un polarizador adecuadamente orientado.
