Abstract

LA INVENCION SE REFIERE A UN PROCESO Y UN DISPOSITIVO PARA LA VERIFICACION DE LA AUTENTICIDAD Y/O IDENTIFICACION DE LA ESTRUCTURA ESPACIAL DE UN OBJETOS A SER INSPECCIONADO. UNA CAPA O SUPERFICIE (6) QUE ES TRANSPARENTE A LAS ONDAS ULTRASONICAS PERO QUE REFLEJA O DIFRACTA LAS ONDAS ELECTROMAGNETICAS ESTA PUESTA EN EL CUERPO (4). ESTA CAPA O SUPERFICIE (6) EN EL CUERPO (5) ESTA DE FORMADA LOCALMENTE Y DE MODO DEPENDIENTE DEL TIEMPO MEDIANTE ONDAS ULTRASONICAS DE ACUERDO CON LA FORMA DE INTENSIDAD DE LAS ONDAS ULTRASONICAS REFLEJADA O DIFRACTADAS, Y ESTA CAPA (6) ES IRRADIADA A UN ANGULO DETERMINADO CON ONDAS ELECTROMAGNETICAS. EN EL AREA DE LA RADIACION REFLEJADA Y/O DIFRACTADA ELECTROMAGNETICA LOCALIZADA BAJO EL ANGULO (9) DE REFLEXION SON DETECTADAS LAS INDICADAS RADIACIONES Y EVALUADA SU MODIFICACION ORIGINADA MEDIANTE LA REFLEXION O DIFRACCION SOBRE LA CAPA (6). PARA IMPLANTAR ESTE PROCESO SE DISEÑA UN DISPOSITIVO DE TAL MODO QUE LAS CAPAS (6) INDICADAS ESTAN DISPUESTAS EN EL CUERPO (4)Y EL DISPOSITIVO (1) TIENE UNA FUENTE (7) DE RADIACION ELECTROMAGNETICA CUYOS RAYOS SON DIRIGIDOS HACIA LA CAPA (6), Y SE DISPONE AL MENOS DE UN RECEPTOR (8) DE RADIACION EN LA ZONA DE LA RACION REFLEJADA O DIFRACTADA ELECTROMAGNETICA PARA LA EVALUACION DE ESTA RADIACION.
