Dynamic Brillouin Sensor in Optical Fibres Using Fast Fourier Analysis and Low-Bandwidth Acquisition

Abstract
A dynamic Brillouin sensor using spontaneous Brillouin scattering and low bandwidth electronics is developed. The Brillouin frequency is obtained by time-division fast Fourier analysis on Brillouin signals, reaching a temperature resolution of 62mK at 1kHz.
