Abstract
Using a short pulse (~ 1 ns) and a pre-injected CW beam as the probe beam in the pump-probe configuration of Brillouin-based distributed sensors, we develop a spectrum deconvolution method, which considers the location correlation of the strain distribution, to find the number of Brillouin peaks and their frequencies in the Brillouin profile and hence achieve accurate strain information at cm spatial resolution.
