Abstract

UN SISTEMA DE PULSO-ECO USA SEÑALES DE ULTRASONIDO PARA DETECTAR DISCONTINUIDADES O FALLOS EN UNA PARED. EL SISTEMA COMPRENDE UN TRANSDUCTOR QUE TRANSMITE SEÑALES DE ULTRASONIDO Y RECIBE LAS SEÑALES DE ULTRASONIDO REFLEJADAS, Y MEDIOS DE REFLEXION (3, 5, 6) QUE COMPRENDEN AL MENOS DOS PLANOS DE REFLEXION (3, 5, 6) QUE CREAN DOS CAMINOS PARA LAS SEÑALES DE ULTRASONIDOS. LOS DOS CAMINOS (12, 13) SE ENCUENTRAN EN LA PARED DE TAL MANERA QUE SON ESENCIALMENTE PERPENDICULAR UNO AL OTRO. EN EL DESPLAZAMIENTO DE UNA DISCONTINUIDAD (4), DONDE LOS DOS CAMINOS SE ENCUENTRAN, LAS SEÑALES DE ULTRASONIDO SE REFLEJAN HACIA ATRAS A LO LARGO DE LOS CAMINOS RESPECTIVOS PARA SER DETECTADAS EN EL TRANSDUCTOR (2), LAS LONGITUDES DE LOS CAMINOS PUEDEN VARIARSE ALTERANDO LAS POSICIONES RELATIVAS DE LOS PLANOS DE REFLEXION. UNO DE LOS CAMINOS (13) PARA LAS SEÑALES DE ULTRASONIDO PUEDE TENER UN COMPONENTE CIRCUNFERENCIAL EN EL INTERIOR DE LA PARED. DE ESTA FORMA PUEDE DETECTARSE UN AMPLIO RANGO DE ORIENTACIONES O DISCONTINUIDADES.
