Working principle of Rayleigh Backscattering optical fiber sensors ...

WebThe theory of backscattering in single-mode optical fibers is described through use of a correlation function for the refractive-index fluctuation in the fiber. A simple formula for the backscattered power is derived using two correlation functions for the Booker–Gordon and Gaussian models. The zeroth-order approximation of the formula, in which the correlation … WebRayleigh- versus Mie- Scattering. The figure 1 shows the different regions applicable to computing the radar cross section of a sphere.
