Abstract

Se proporciona un dispositivo óptico de seguridad que incluye un sustrato transparente o translúcido, al menos una primera matriz de elementos repetitivos en o sobre un primer lado del sustrato, al menos una segunda matriz de elementos repetitivos sobre un segundo lado del sustrato. La segunda matriz de elementos repetitivos está sustancialmente en registro con la primera matriz de elementos, por lo cual una primera imagen es visible cuando se ve el dispositivo desde el primer lado, y una segunda imagen es visible cuando se ve el dispositivo desde el segundo lado. Los niveles de brillo o color de los elementos de imagen que se repiten sobre al menos un lado del sustrato se pueden modular en el sentido de la región para producir una imagen a escala de grises o color. En una modalidad, la primera matriz de elementos repetitivos en o sobre un primer lado del sustrato es una matriz de elementos que se enfocan, y la segunda matriz de elementos repetitivos en o sobre el segundo lado del sustrato es una matriz de imagen que tienen de manera sustancial la misma forma la una a la otra, de modo que, cuando se el dispositivo se ve desde el primer lado, una imagen ampliada que incluye al menos una versión ampliada de la forma de elemento de imagen es visible, y cuando se ve el dispositivo desde el segundo lado, la imagen a escala de grises o de color es visible. En otra modalidad, los elementos repetitivos de ambas de la primera y segunda matrices son elementos de imagen parcialmente o totalmente opacos los cuales respectivamente forman la primera y segunda imágenes.
