Abstract
Un dispositivo de seguridad que comprende una estructura de generación de efecto holográfico ópticamente variable que tiene por lo menos dos secciones discretas las cuales generan, en respuestas a iluminación de luz blanca, una imagen ópticamente variable que consiste en por lo menos dos elementos gráficos definidos localizados en o cerca de, un plano imagen, ya sea sobre o adyacente al plano del dispositivo, y las cuales, en respuesta a iluminación coherente, generan por lo menos dos imágenes discretas, en forma de señal, cuyos planos imagen están ubicados a una distancia lejos del plano real del dispositivo, donde son reconstruidas las imágenes secretas a diferentes ángulos con respecto a una normal a un substrato que soporta el dispositivo de modo tal que las imágenes secretas están espacialmente separadas sobre su plano imagen, y las imágenes secretas no son visibles con iluminación de luz blanca.<EMI FILE="00040653_1" ID="1" IMF=JPEG >A security device comprising an optically variable holographic effect generation structure having at least two discrete sections which generate, in responses to white light illumination, an optically variable image consisting of at least two defined graphic elements located at or near an image plane, either above or adjacent to the device plane, and which, in response to coherent lighting, generate at least two discrete images, in the form of a signal, whose image planes are located at a distance away from the real plane of the device, where the secret images are reconstructed at different angles with respect to a normal one to a substrate that supports the device such that the secret images are spatially separated on their image plane, and the secret images are not visible with white light illumination. <EMI FILE = "00040653_1" ID = "1" MFI = JPEG>
