Abstract: Dispositivo para el análisis espectral de señales ópticas basado en el efecto de Difusión Brillouin Estimulada y procedimiento de medida asociado que utiliza la amplificación óptica de las señales por el propio efecto de Difusión Brillouin. El efecto de Difusión Brillouin permite la amplificación óptica selectiva de una determinada componente del espectro óptico de la señal a analizar, que se denominará señal problema, para su medida con una resolución, sensibilidad y rango dinámicos determinados. La señal problema se introduce en una fibra óptica conjuntamente con una señal óptica de banda estrecha, que denominaremos señal sonda, centrada en una determinada longitud de onda, que se propaga en sentido contrario al de la señal problema interaccionando ambas señales, debido al efecto Brillouin, en el interior de la fibra.

Abstract: The invention relates to a device which is used for the spectral analysis of optical signals and which is based on the stimulated Brillouin scattering effect. The invention also relates to the associated measurement method which makes use of the optical signal amplification caused by the Brillouin scattering effect. The Brillouin scattering effect enables the selective optical amplification of a determined component of the optical spectrum of the signal to be analysed, known as the problem signal, for the measurement thereof with a determined dynamic range, sensitivity and resolution. According to the invention, the problem signal is introduced into an optical fibre together with a narrowband optical signal, known as the probe signal, within a determined wavelength. Said probe signal propagates in the opposite direction to that of the problem signal, such that both signals interact inside the fibre owing to the Brillouin effect.

Abstract: A distributed vibration sensing technique based on Backscattered Rayleigh light (402) is disclosed, enabling the measurement of greater optical fiber (400) lengths by using one or more regeneration modules (200) in which the optical light pulses (401) emitted by a master device (100) are received, conditioned and transmitted again into another optical fiber (400) segment. Pulse conditioning may comprise, for example, reshaping, filtering, amplification and isolation. Each regeneration module (200) further comprise detection means that receive the Backscattered Rayleigh light (402) of the next optical fiber (400) segment. That is, each optical fiber (400) segment is independently detected by a regeneration module (200), which then transmits the sensing information to a central server (600) through a communication network (500).
