This paper studies the Brillouin optical time domain analysis system, sums up the important parameters of the system in the Brillouin optical time domain analysis system, and understands the direction of system optimization. Through the reference of the literature, we can understand how the Brillouin scattering occurs in the time domain system, and select the parameters to achieve the sensing distance and sensitivity optimization. The data processing of the system backend is also developed. This paper also studies and analyzes the influence of temperature on Brillouin frequency shift and Brillouin optical time domain analysis system combined with fiber grating. Firstly, the development and importance of distributed fiber sensing and Brillouin optics are also introduced. Different fiber sensing principles and methods and different scattering effects and applications in optical fibers are introduced.
In the middle section, we will gradually analyze how to interpret the meaning of optical signals and electrical signals, and explore the best basic parameters by principle and experiment, such as: the ratio of pump light intensity between probe light intensity, Brillouin gain spectrum, Brillouin scattering system, the effect of pulse width on the Brillouin gain spectrum, and the filtering wavelength of the tunable filter are studied and analyzed. The system operation flow is established, and Matlab is used as the application software for data reading. The data is imported into Matlab for drawing, and by programming the code and establishing a set of processes, the experimental results are obtained more quickly, and the reference data (undisturbed single-mode fiber) and measurement data (disturbed single mode) are imported. The fiber is operated to allow the result to simultaneously display the measured data map and the location of the disturbance.
This paper attempts to lengthen the measurement distance and shorten the irregular area to improve the spatial resolution. Finally, the length measurements of 3.6km, 5.6km, 10km and 15km are obtained, and the spatial resolution of 15km SMF / 4m DSF is obtained. The influence of temperature on Brillouin frequency shift and Brillouin optical time domain analysis system combined with fiber grating were carried out to study and analyze the system design.
