  • Methods and apparatuses for quantitative sensing using Rayleigh scattering in optical fiber
    Patent number: 11788908
    Abstract: Methods and apparatuses for quantitatively measuring strain in an optical fiber. An optical source comprising an optical beam generator and a pulse generator receives instructions from a controller and generates a pulsed optical beam in response to those instructions. The pulsed optical beam is directed into an optical fiber to generate a reflected beam from scattering centers within the optical fiber. A detector records a plurality of frames of data generated by the reflected beam, and the controller tracks an evolution of a speckle pattern carried by the reflected beam from the plurality of frames and calculates a strain induced in a section of the optical fiber from the evolution of the speckle pattern.
