Abstract
SISTEMA DE DETECCION DE IMPERFECCIONES EN BLINDAJES CONTRA RADIACION ELECTROMAGNETICA, EN EL QUE SE EMPLEA UN CAMPO GIRATORIO MAGNETICO (O ELECTRICO) QUE SE GENERA FUERA (O DENTRO) DEL BLINDAJE MEDIANTE, POR EJEMPLO, PARES DE BOBINAS DE HELMHOLTZ (13,15;14,16) QUE ESTAN EN ANGULO (DE, POR EJEMPLO, 90 GRADOS) ENTRE SI Y QUE SE ACCIONAN POR UNA SEÑAL MODULADA. LA FASE DE MODULACION DE LOS PARES RESPECTIVOS DE BOBINAS DIFIEREN ENTRE SI EN UN VALOR IGUAL A LA DIFERENCIA ENTRE LOS ANGULOS RESPECTIVOS DE DICHOS PARES DE BOBINAS. EL CAMPO QUE PENETRA A TRAVES DEL BLINDAJE (2) SE DETECTA EN VARIAS DIRECCIONES POR UNO DETECTOR (10). EN LAS DIRECCIONES EN LAS QUE LA INTENSIDAD DE CAMPO ES RELATIVAMENTE ALTA EL BLINDAJE PUEDE EXAMINARSE MAS ATENTAMENTE CON MEDICIONES LOCALES. EN COOPERACION CON UNA ALARMA, EL SISTEMA DE DETECCION PUEDE UTILIZARSE COMO SISTEMA DE PROTECCION CONTRA DESPERFECTOS EN EL BLINDAJE DE UN ALOJAMIENTO (22) CAUSADO, POR EJEMPLO, POR ROBO. CUANDO SE DETECTA QUE LA PENETRACIONDEL CAMPO A TRAVES DEL BLINDAJE AUMENTA (DEBIDO AL DAÑO SUFRIDO POR DICHO BLINDAJE), SE ACTIVA UNA ALARMA.
