Abstract

UN SENSOR DE ROTACION DE FIBRAS OPTICAS TENIENDO UNA BOBINA (10) DE FIBRAS DE MODO UNICO, CON UN DESPOLARIZADOR (10'') EN SERIE CON EL, CONFIGURADO CON LONGITUDES DE PASO OPTICO COMPONENTES EN EL Y RELACIONES DE EJES BIRREFRINGENTES EN EL, ELEGIDAS CON RESPECTO A LA AUTOCORRELACION DE FUENTES. PUEDEN ELIMINARSE ERRORES DE FASE RELACIONADOS CON LA AMPLITUD, DEBIDO AL ACOPLAMIENTO DEL MODO DE POLARIZACION, O REDUCIRSE ECONOMICAMENTE, Y PUEDE EVITARSE SUSTANCIALMENTE EL DESVANECIMIENTO DE LAS SEÑALES.
