Abstract

UN DOCUMENTO (10) SE CUBRE MEDIANTE UN LAMINADO (13) QUE COMPRENDE UNA CAPA DE MICROESFERA (16) SOBRE UNA CAPA DE ADHESIVO (14) QUE CUBRE UNA IMAGEN FUENTE (12) TAL COMO UNA FOTOGRAFIA, UNA FIGURA IMPRESA O UN CODIGO DE BARRAS DISPUESTAS SOBRE UN SUBSTRATO (11). LA LUZ QUE INCIDE SOBRE EL DOCUMENTO (10) ES DIVIDIDA POR LAS PROPIEDADES OPTICAS DE LAS MICROESFERAS (16) Y DE REFLECTORES ESPECULARES SUBYACENTES. LA LUZ RESTANTE PASA A TRAVES DE LAS MICROESFERAS (16), A TRAVES DE LA CAPA DE ADHESIVO (14) E INCIDE EN EL SUBSTRATO (11) O EN UNA IMAGEN FUENTE (12) SOBRE EL DOCUMENTO (10) Y ES REFLEJADA (18) Y DISPERSADA (20). ALTERNATIVAMENTE, EL LAMINADO (13) PUEDE COMPRENDER UNA CAPA DE POLIESTER SIN MICROESFERAS SOBRE LA CAPA DE ADHESIVO (14). LA LUZ QUE INCIDE SOBRE EL LAMINADO (13) PASA A TRAVES DEL POLIESTER Y EL LAMINADO (14) PARA INCIDIR EN EL SUBSTRATO (11) O EN LA IMAGEN FUENTE (12) EN DONDE ES REFLEJADA Y ESPARCIDA. UNA PRIMERA FUENTE DE LUZ (24) DIRIGE LUZ SOBRE EL DOCUMENTO (10). UNA SEGUNDA FUENTE DE LUZ (26, 27) DIRIGE LUZ HACIA UN ESPEJO DE DIVISION DEL RAYO DE LUZ (23) QUE REFLEJA LA LUZ HACIA EL DOCUMENTO (10). LAS PROPIEDADES DE RETORNO DE LA LUZ DEL ESPEJO (23) PRODUCEN UNA FUENTE DE LUZ QUE APARECE PARA UN RECEPTOR DE IMAGENES (40) COMO QUE ES DE VUELTA DESDE LA SUPERFICIE DEL DOCUMENTO EN UN ANGULO INFERIOR A 1 (GRADOS) . EL RECEPTOR DE IMAGENES (40) PASA UNA SEÑAL POR MEDIO DE UNA LINEA (32) A UN ORDENADOR PERSONAL (41) QUE PROCESA LA INFORMACION RECIBIDA. EL PROCESAMIENTO ESTABLECE CUANDO EL DOCUMENTO (10) INCLUYE UN LAMINADO RETRORRECEPTOR, UNA LAMINA DE POLIESTER PLANA O NADA. ADICIONALMENTE, UN PROCESAMIENTO ADICIONAL PUEDE ESTABLECER CUANDO EL DOCUMENTO (10) HA SIDO MANIPULADO, ALTERADO O FALSIFICADO.
