Fiber optic sensors based on stimulated Brillouin scattering (SBS) have gained much attention in recent years owing to their unparalleled ability to continuously evaluate a measurand of interest, such as strain or temperature, along an optical fiber. The possibility to extending the use of distributed optical fiber sensors to dynamic measurements would be of special interest in some application fields, such as measurement of vibrations in civil or aeronautic structures. A few studies have been made on SBS-based fiber optics sensors capable of real-time structural monitoring applications that require a sensor response in the range of seconds or less.
