The working principle is as follows: stress-strain detection principle based on Brillouin scattering in scheme
The brillouin scattering has a brillouin frequency shift relative to the transmitted light, and the formula is expressed as follows: where ω L is the frequency of incident light, ω S is the frequency of scattered light, and Ω B is an equivalent density grating moving at a constant speed VB, that is, a so-called brillouin frequency shift. Ω B is related to the temperature and strain of the optical fiber, and the specific relationship is as follows:
wherein T and epsilon are temperature and strain respectively, n, E, k and rho are refractive index, Young modulus, Poisson's ratio and density of the optical fiber respectively, and lambdap is the wavelength of incident light.

And adopting an optical time domain reflection technology for space positioning.
Technical location relationship
The light source emits a very narrow high intensity light pulse of a certain frequency into the sensing fiber. The propagation of incident light in the fiber produces backscattered light. Over time, the backscattered light returns and is detected. Starting from when the light pulse enters the fiber, and when the light reaches z and the scattered light returns to the point of incidence, the position in the fiber where the scattering occurs and the time taken for the point-changed scattered light to return have the following relationship:
raman scattering contains a stokes light which is not sensitive to temperature and an anti-stokes light which is sensitive to temperature, and is formulated as follows:
stokes scattered light intensity:
anti-stokes scattered light intensity:
stokes scattered light frequency:
anti-stokes scattered light frequency:
wherein: c is 3 × 108m/s, which is the speed of light in vacuum; h is 6.63 multiplied by 10-34J.s which is ordinary-cooked Planck; k is 1.38 × 10-23J/K is boltzmann's constant; v is the Raman shift wavenumber of the fiber, and the quartz fiber is 44000 m-1; λ s, λ a and λ are the stokes scattered light wavelength, anti-stokes scattered light wavelength and incident light wavelength, respectively; λ is the vibration frequency of the fiber molecules, i.e., the raman shift.
