Abstract

A distributed strain measurement with millimeter-order spatial resolution was demonstrated in optical fibers based on Brillouin optical correlation-domain reflectometry (BOCDR) employing a tellurite glass fiber as the fiber under test. First, the dependences of Brillouin frequency shifts (BFSs) on strain and temperature in the tellurite fiber were investigated, and they showed negative dependences with coefficients of -0.023 MHz/με and -1.14 MHz/K, respectively. Then, using this tellurite fiber, the BFSs around 1-cm strain-applied section were successfully measured based on BOCDR with a nominal spatial resolution of 6 mm.
