Abstract

LA INVENCION SE REFIERE A UN EXPLORADOR DE LINEAS CCD PARA EXPLORACION ELECTROOPTICA DE UN OBJETO (12), EN PARTICULAR PARA REGISTRO AUTOMATICO DE DOCUMENTOS O TARJETAS DE CHEQUEO, COMPONIENDOSE DE UN EQUIPO DE ILUMINACION EN FORMA DE UN ESPEJO (1,2,3) CURVADO DE FORMA CONCAVO, CON LAMPARAS (7,7''), UN OBJETIVO (8) OPTICO Y AL MENOS UN SENSOR (10,10'') DE LINEAS CCD DISPUESTO CON EL. EL ESPEJO (1,2,3) ESTA CURVADO DE FORMA ELIPTICA, EN EL QUE SE DISPONE DE UN PUNTO (F1) DE REFRACCION CON DOS LAMPARA (7,7'') Y UN SEGUNDO PUNTO (F2) DE REFRACCION QUE SE ENCUENTRA EN EL PLANO DEL OBJETO (12) A SER EXPLORADO. EN LA ZONA DE UN VERTICE Y EN PROYECCION PREVISTA ENTRE LAS LAMPARAS (7,7''), EL ESPEJO (1,2,3) MUESTRA UNA ROTURA (4) EN FORMA DE ESPACIO DE DISTANCIA PARA SUPRESION DE ECOS DE LA VIA (6) DE RADIACION DE FORMACION DE IMAGEN HACIA EL EXTERIOR DEL ESPEJO (1,2,3), DONDE EN LA VIA (6'') DE RADIACION DE FORMACION DE IMAGEN EXTERIOR SE ENCUENTRA DESPUES DE LA ROTURA (4) EL OBJETIVO (8), EN CUYO PLANODE IMAGEN SE DISPONE EL SENSOR (10,11) DE LINEAS.
