Abstract
Sensor de medida de la distribución de magnitudes físicas en una fibra óptica y procedimiento de medida asociado. Sensor de medida de la distribución de magnitudes físicas en una fibra óptica (7) que comprende un generador de señales ópticas (1), un dispositivo de pulsación (70) y un generador de onda de prueba (5), que dan lugar a, al menos, una señal óptica de bombeo pulsada (H) y, al menos, una señal óptica de prueba (I); un segmento de fibra óptica (7) donde las señales ópticas de bombeo pulsada (H) y prueba (I) interaccionan entre sí; comprendiendo además el sensor un conjunto de reducción de efectos no locales y de aumento del umbral de Brillouin provisto de un generador de señal de modulación (2) que permite modular en longitud de onda al menos una de las señales ópticas de prueba I y/o al menos una señal óptica de amplificación (J).
