| Research Abstract |
BOTDA is an optical fiber sensor for measuring distributed temperature and strain by utilizing the dependence of stimulated Brillouin scattering frequency shift on them. In order to improve SNR and achieve faster measurement for BOTDA, this study has proposed two techniques: structured coding and spectrum control. It has been clarified theoretically and experimentally that both techniques are effective to improve the BOTDA performance.
