Rayleigh shift
Webwill receive energy that is of the same frequency as the excitation source; this is known as Rayleigh or elastic scattering. A very small amount of the scattered light (~ 1 in 107) is shifted in energy from the laser frequency. This shift is known as a Raman or Stokes shift. At room temperature, the anti-Stokes-shifted Raman energy is WebJul 26, 2024 · DSS-RFS is different from other FO strain measurements because it relies on accurate measurement of frequency shifts of Rayleigh backscattered spectrum obtained by scanning the fiber with a coherent optical time-domain reflectometer with a range of laser frequencies using a tunable-wavelength laser system.
