A Method for Peak Seeking of BOTDR Based on the Incomplete Brillouin Spectrum
Distributed fiber sensing technology based on a Brillouin optical time domain reflectometer is widely applied for health monitoring in engineering. However, it cannot perceive quick external interference. In this paper, we propose to use polynomial fitting on the inverse of an incomplete Brillouin s...

| description | Distributed fiber sensing technology based on a Brillouin optical time domain reflectometer is widely applied for health monitoring in engineering. However, it cannot perceive quick external interference. In this paper, we propose to use polynomial fitting on the inverse of an incomplete Brillouin spectrum and find the peak frequency by statistical analysis. Simulation results show that the peak frequency obtained by our method is only 1.096 MHz higher than that by using the Lorenz fitting method on a whole discrete Brillouin spectrum. The method has high accuracy, good repetitiveness, and high stability and is helpful in health monitoring for situations with interference that lasts for a short time. |
