| Abstract(in English) | Brillouin gain spectrum distribution along an optical fiber is measured using frequency-modulated pump and probe lightwaves. This technique enables realization of a high spatial resolution because the resolution is not limited by the phonon lifetime. In this presentation, measurement principle is described based on the coupled equations of stimulated Brillouin scattering. Then, a spatial resolution under 10 cm is demonstrated experimentally for the first time. Finally, it is shown that the uncorrelated gain degrades the accuracy for Brillouin frequency shift, and its elimination by the numerical treatment based on deconvolution is demonstrated on the experimental result. |
