Abstract
In this paper the method for interrogation of Brillouin scattering signal from sensing fiber is proposed. The essence of the method consists in the application of the single pump source to generate reference signal due stimulated Brillouin scattering in thermally stabilized reference fiber spool and for probing the sensor fiber. As result of heterodynes in receiver the signal at beat frequencies is analyzed. The requirements for pump power and reference fiber parameters are defined theoretically and experimentally. The results of experimental estimation of beat signal are represented.
