Fast Brillouin Optical Time Domain Analysis Measurement Based on Broadband Probe Light

This article focuses on distributed vibration measurement based on Brillouin optical time-domain analysis (BOTDA). We propose a new method to obtain the frequency spectrum of Brillouin scattering using broadband light as a probe light of BOTDA and coherent detection. By using the proposed method, th...
