Abstract
System and method of distributed sensing based on Brillouin stimulated scattering on optical fiber (), consisting of separating the two signals of which the probe signal is composed and obtaining the difference between the stimulated amplification band () and the attenuation band (), or vice-versa. In this way a signal is obtained with greater amplitude than in the case of detection being performed with a single band. Thus the signal-to-noise ratio is improved in the sensor signal, dynamic range and the range is increased and the uncertainty of the measurement is decreased. It also eliminates the common noise present in the two bands of the probe signal and, in the case of using a balanced detector in detection, it improves the saturation characteristics of the detector, being able to achieve much larger signal amplitudes than in the conventional case.
