Abstract
LA INVENCION SE REFIERE A UN DISPOSITIVO DE MEDIDA DE FIBRA OPTICA DEL TIPO EN EL CUAL LA VARIACION DE UN PARAMETRO MEDIDO GENERA UNA DIFERENCIA DE FASE ENTRE DOS ONDAS EN UN INTERFEROMETRO EN ANILLO DE SAGNAC (2). UNOS MEDIOS ELECTRONICOS (7) TIENEN UN SISTEMA DE TRATAMIENTO (9) QUE DA UNA SEÑAL FUNCION DEL PARAMETRO MEDIDO Y UNOS MEDIOS ELECTRONICOS (12) QUE MANDAN EL MODULADOR DE FASE (4). LOS MEDIOS ELECTRONICOS (12) TIENEN UNA SEÑAL DE MANDO DEL MODULADOR DETERMINADO DE TAL MODO QUE LA DIFERENCIA DE FASE DELTA PHI SUB M QUE PRODUCE ENTRE LAS ONDAS CONTRA-PROPAGATIVAS TOMA PERIODICAMENTE LOS CUATRO VALORES SIGUIENTES: DELTA PHI SUB 1 = PHI SUB 0 DELTA PHI SUB 2 = A PHI SUB 0 DELTA PHI SUB 3 = -PHI SUB 0 DELTA PHI SUB 4 = -A PHI SUB 0 EN LAS CUALES PHI SUB 0 ES UN DESFASE CONSTANTE Y DEPENDIENTE DE A, DONDE A ES UNA CONSTANTE POSITIVA QUE SATISFACE LA CONDICION SIGUIENTE: COS PHI SUB 0 = COS A PHI SUB 0. SE MANTIENE CONSTANTE LA GANANCIA DE LA CADENA DE MANDO DE LA MODULACION AL PRODUCIRUNA SEÑAL FUNCION DE DICHA GANANCIA EXPLOTANDO LOS CUATRO VALORES X1, X2, X3, X4 DADOS COMO RESPUESTA A UN PERIODO DE SEÑAL DE MODULACION SEGUN LA FORMULA (X1 + X3) DICHA SEÑAL ACTUANDO SOBRE EL MODULADOR DE MODO QUE MANTIENE LA GANANCIA CONSTANTE.
