Rayleigh-Ritz methods for the approximation of the natural modes for a class of vibration problems involving flexible beams with tip bodies using subspaces of piecewise polynomial spline functions are ...

Sensitive detectors monitor the change in the Rayleigh backscatter created by the varying core density and turn it into a representation of the detected vibration.

Rayleigh scattering is used for vibration sensing and also acts as the probe of Brillouin scattering process to realize temperature and strain measurement.
