Abstract

SI SE CONTROLA EL CAMPO ELECTROMAGNETICO DE LA CARGA DE LA FIBRA OPTICA A MEDIDA QUE PASA POR UNA ANTENA, SE CUENTAN LAS VUELTAS DE UNA FIBRA OPTICA QUE SE DESENRROLLA DE UN CANASTILLO Y SE MIDE LA CARACTERISTICA MAGNETICA DE LA FIBRA OPTICA. LA FIBRA OPTICA SIGUE UNA TRAYECTORIA HELICOIDAL A MEDIDA QUE SE DESARROLLA. UNA ANTENA FIJA QUE SE ENCUENTRA COLOCADA DE FORMA TRANSVERSAL PROXIMA A LA ZONA DE DESENROLLADO DETECTA UNA VARIACION DE REPETICION PERIODICA DE LA CARGA LATENTE Y/O CARGA ELECTRICA LIBRE ASOCIADA A LA FIBRA OPTICA, A MEDIDA QUE LA FIBRA OPTICA SE JUNTA Y SE ALEJA DE LA ANTENA A LO LARGO DE LA TRAYECTORIA HELICOIDAL. CADA PERIODO DE LA VARIACION CORRESPONDE A UNA VUELTA DE LA FIBRA OPTICA DESENROLLADA DEL CARRETE.
