The strain dependence of the Brillouin gain–loss spectrum for PANDA, bow-tie, and tiger polarization-maintaining fibers has been studied in the range 0 to 50°C. We found a linear relationship between the strain and the Brillouin frequency, intensity, and bandwidth for PANDA and bow-tie fibers. For PANDA fiber at 20-cm spatial resolution, Brillouin frequency gives 7-μ∈ uncertainty, which is the highest accuracy among three parameters, whereas the Brillouin bandwidth gives 19-μ∈ uncertainty.
