Dual-source distributed optical fiber sensor for simultaneous temperature and strain measurements
Abstract
A dual-source distributed optical fiber sensor system with combined Raman and Brillouin scatterings is designed for simultaneous temperature and strain measurements. The optimal Raman and Brillouin signals can be separately obtained by adjusting the powers of the two sources using an optical switch. The temperature and strain can be determined by processing the optimal Raman and Brillouin signals. The experimental result shows that 1.7 ℃ temperature resolution and 60-με" strain resolution can be achieved at a 24.7-km distance.
