A high resolution distributed dynamic strain sensing has been proposed and experimentally demonstrated based on the combination of Brillouin and Rayleigh scattering. The proposed scheme employs the same set of frequency-scanning optical pulses modulated through the frequency-agile technique for fast measurements. The Brillouin optical time domain analyzer (BOTDA) technology is used to provide absolute measurement benchmarks, while the phase-sensitive optical time domain reflectometer (φ-OTDR) technology is used to capture relative strain changes in details. Two groups of 100 Hz vibrations with different amplitude (300 nε and 250 nε) have been measured under two different absolute strains (1173.9 με and 525.3 Με), which allows for dynamic absolute strain measurement with a high resolution of 8.4 nε.
