Abstract

PORTADOR DE INFORMACION OPTICA (1) EN FORMA DE ESTRATO DE MATERIAL COMPOSITE (2) QUE POSEE UNA HOJA PORTADORA (3). LAS CARAS INFERIOR (4) Y SUPERIOR (5) DE LA HOJA PORTADORA (3) POSEEN ESTRUCTURAS OPTICAMENTE EFECTIVAS (6; 7). LA HOJA PORTADORA (3) ES PRACTICAMENTE TRANSPARENTE PARA LA LUZ EN UN RANGO ESPECTRAL DETERMINADO. LAS ESTRUCTURAS (7) PERMITEN A LA LUZ INCIDENTE SOBRE LA CARA SUPERIOR (5) PENETRAR, AL MENOS PARCIALMENTE, EN EL ESTRATO DE COMPOSITE (2). LAS ESTRUCTURAS (6) DE LA CARA INFERIOR (4) SON ESTRUCTURAS EN RELIEVE MICROSCOPICAMENTE FINAS (10) CUBIERTAS CON UNA CAPA BASE (8) CUYO INDICE DE REFRACCION ES DIFERENTE DEL INDICE DE REFRACCION DE LA HOJA PORTADORA (3), AL MENOS EN UNA REGION DEL ESPECTRO ELECTROMAGNETICO, DE FORMA QUE LAS ESTRUCTURAS (6) DE LA CARA INFERIOR (4) REFLEJEN Y DIFRACTEN, AL MENOS PARCIALMENTE, LA LUZ (11) QUE HA PENETRADO EN EL ESTRATO DE COMPOSITE (2). LAS ESTRUCTURAS (7) DE LA CARA SUPERIOR (5), MODIFICAN, A SU VEZ, LA LUZ DIFRACTADA (18). LA INTERACCION DE LAS DOS ESTRUCTURAS (6; 7) PROPORCIONA MULTIPLES EFECTOS OPTICOS CARACTERISTICOS, TALES COMO EFECTOS MOIRE Y EFECTOS DE GUIA DE LUZ. TAMBIEN ES POSIBLE, DE ESTA FORMA, CONSEGUIR DISPOSITIVOS DE ALMACENAMIENTO OPTICO, RETRORREFLECTORES Y OTROS ELEMENTOS DE SEGURIDAD, ESTANDO BIEN PROTEGIDOS FRENTE A ACCESOS NO AUTORIZADOS.
