Abstract
In this work we demonstrate high spatial (≈cm) and spectral (≈MHz) resolution Brillouin sensing by use of Brillouin Optical Frequency-Domain analysis (BOFDA). The employed set-up was capable to resolve a 3cm spot perturbation at the far end of a 210m fiber with a frequency resolution of 0.84MHz. The method has potentialities for mm-scale spatial resolution and long sensing ranges.
