An all-fiber system for simultaneous interrogation of distributed strain and temperature sensing using spontaneous Brillouin scattering
We demonstrate a low-loss, long-range, single-ended distributed optical fiber sensor to measure both temperature and strain simultaneously and unambiguously. By using the Landau-Placzek ratio and cascaded Mach-Zehnder interferometric filters, we measure both the intensity and the frequency changes i...
