Paper Abstract
In this paper we propose the employment of sub-pixel algorithms for the estimation of the central frequency of the
Brillouin Gain Spectrum in a Brillouin Optical Time Domain Analyzer. The experimental results will show that the
proposed solution shows a good performance when the chosen frequency step for the required frequency sweep is high.
If the improved computational efficiency in comparison to the traditional Lorentzian fitting is also considered, it can be
concluded that this approach may be of great interest for dynamic measurement scenarios.
