Abstract
We propose a simple and cost-effective technique that can reduce the electrical bandwidth for Brillouin frequency-shift sensors with heterodyne detection without the need for expensive instruments or a complicated system. With this technique we use only a reference fiber. The reference Brillouin scattering light in the reference fiber is used as a local light for heterodyne detection. We confirm that this method can be used for measuring the Brillouin scattering spectrum distribution with a much lower frequency bandwidth (
