Abstract

We present, for the first time to our knowledge, the use of multiple axial laser modes in distributed temperature sensing based on stimulated Brillouin scattering. One axial mode stimulates a Stokes wave with a temperature-dependent Brillouin frequency shift in the 13-GHz range. Optical heterodyning of the stimulated Stokes wave with a second axial laser mode allows one to generate and evaluate a beat signal in a lower frequency range. Using diode-pumped solid-state lasers, we have reduced the Brillouin beat frequency to the 500-MHz range. Hence, low-cost detectors and conventional signal-processing techniques can be applied for the beat signal processing.
