    Abstract: Various embodiments include apparatus and methods to measure a parameter of interest using a fiber optic cable. The parameters can be provided by a process that provides for multiplexed or distributed measurements. A multiplexed or a distributed architecture can include acoustic sensor units placed selectively along an optical fiber such that the acoustic sensor units effectively modulate the optical fiber with information regarding a parameter to provide the information to an interrogator coupled to the optical fiber that is separate from the acoustic sensor units.

    Abstract: Systems and methods for distributed acoustic sensing based on coherent Rayleigh scattering are disclosed herein. A system comprises a pulse generator, an optical fiber coupled to the pulse generator, an interferometer coupled to the optical fiber, a photodetector assembly coupled to the interferometer, and an information handling system, which activates two optical gain elements so as to vary the optical path length of the interferometer. A method comprises sending an optical pulse down an optical fiber, splitting backscattered light from the optical pulse into a first backscattered pulse and a second backscattered pulse, activating a first optical gain element and a second optical gain element, sending the first backscattered pulse into a first arm of an interferometer, sending the second backscattered pulse into a second arm of an interferometer, combining the first and second backscattered pulses to form an interferometric signal, and receiving the interferometric signal at a photodetector assembly.
