Abstract

PARA ASEGURAR UNA CORRIENTE (I) EN UN CONDUCTOR (2) LA INVENCION PROPONE QUE DOS SEÑALES (S, T) DE LUZ DIRIGIDAS DE FORMA OPUESTA SE TRANSMITAN A TRAVES DE UN ELEMENTO (3) FARADAY RODEANDO EL CONDUCTOR (2) Y, DESPUES DE PASAR A TRAVES DEL ELEMENTO (3) FARADAY, SE DISTRIBUYA EN DOS COMPONENTES. A PARTIR DE CADA UNO DE ESTOS DOS COMPONENTES (S, T) SE DERRIBA UNA SEÑAL CUYA INTENSIDAD ES NORMALIZADA (PS, PT). EL ELEMENTO (3) FARADAY UTILIZADO TIENE UNA BIRREFRINGENCIA CIRCULAR DESPRECIABLE Y EL DISPOSITIVO INCLUYE UNA UNIDAD DE PROCESADO DE SEÑAL PARA DERIVAR UNA SEÑAL (M) DE MEDICION INDEPENDIENTE DE LA VIBRACION Y TEMPERATURA.
