Abstract

La presente invención se refiere a elementos ópticos con microestructuras de relieve de superficie con patrones anisotrópicos en las cuales se codifica información en la distribución de la orientación de diferentes zonas; a partir del análisis de la distribución de la luz dispersada del elemento, se puede evaluar la distribución de orientación en el elemento de acuerdo con la invención y, por lo tanto, la información codificada; los elementos de acuerdo con la invención son particularmente útiles para asegurar documentos y artículos contra falsificación e imitación.
