Resumen
We present a novel Brillouin spectra characterization method based on the Brillouin frequency shift dependence with pump wavelength. It is applied to a Brillouin optical time domain analysis sensor, resulting in a cost effective experimental setup that also avoids pulse leakage distortion in the measured spectra.
