Abstract

Se describe un dispositivo de seguridad, que comprende: un arreglo de estructuras de enfoque alargadas, los ejes alargados de las cuales se alinean a lo largo de una primera dirección, las estructuras de enfoque alargadas que se arreglan paralelas entre si periódicamente a lo largo de una segunda dirección que está ortogonal a la primera dirección, cada estructura de enfoque alargada que tiene una huella óptica de la cual diferentes tiras alargadas serán dirigidas al visualizador en dependencia al ángulo de visualización, la línea central de cada huella óptica que está paralela con la primera dirección; y un arreglo de elementos de imagen que se sobreponen al arreglo de estructuras de enfoque alargadas, el arreglo de elementos de imagen que representan cortes de imagen alargados de por lo menos dos imágenes respectivas, cada corte de imagen que comprende uno o más elementos de imagen, y por lo menos un corte de imagen de cada imagen respectiva que se ubica en la huella óptica de cada estructura de enfoque alargada. El arreglo de elementos de imagen se configura tal que la distancia en la segunda dirección en cada corte de imagen de la línea central de una huella óptica en la cual se ubica el corte de imagen cambia a lo largo de la primera dirección. En por lo menos algunos ángulos de visualización, la tira alargada de la huella óptica de cada estructura de enfoque alargada que se dirige al visualizador incluye una porción de un primer corte de imagen correspondiente a una primera imagen y una porción de un segundo corte de imagen correspondiente a una segunda imagen, tal que la primera imagen es exhibida por una primera región del dispositivo de seguridad y la segunda imagen es exhibida por una segunda región del dispositivo de seguridad que se desalinea lateralmente de la primera región en la primera dirección, las posiciones de la primera y segunda regiones a lo largo de la primera dirección que dependen del ángulo de visualización.
