High-accuracy Brillouin frequency shift measurement system based on stimulated Brillouin scattering phase shift

Near-forward Stimulated Brillouin Scattering

LLE Review, Volume 72 177 In stimulated Brillouin scattering1 (SBS) an incident (pump) light wave is scattered by the electron-density fluctuations associated with an ion-acoustic (sound) wave. This process generates a frequency-upshifted (anti-Stokes) light wave and a frequency-downshifted (Stokes) light wave. For most scattering angles the anti-Stokes wave is driven nonresonantly and can be n...

Stimulated Brillouin Scattering Microscopic Imaging

Two-dimensional stimulated Brillouin scattering microscopy is demonstrated for the first time using low power continuous-wave lasers tunable around 780 nm. Spontaneous Brillouin spectroscopy has much potential for probing viscoelastic properties remotely and non-invasively on a microscopic scale. Nonlinear Brillouin scattering spectroscopy and microscopy may provide a way to tremendously accele...

Suppression of Stimulated Brillouin Scattering

Distributed Pressure and Temperature Sensing Based on Stimulated Brillouin Scattering

Brillouin scattering has been verified to be an effective mechanism in temperature and strain sensing. This kind of sensors can be applied to civil structural monitoring of pipelines, railroads, and other industries for disaster prevention. This thesis first presents a novel fiber sensing scheme for long-span fully-distributed pressure measurement based on Brillouin scattering in a side-hole fi...
