Distributed fiber optic acoustic sensor
9 Nov 21
One example coherent optical time domain reflectometer device includes a coherent light source that produces coherent probe light pulses at an optical wavelength; an optical coupling unit coupled to f a fiber link under test to direct the coherent probe light pulses into the fiber link and to receive reflected probe light pulses from the fiber link; an optical detection unit to receive the reflected probe light pulses and structured to include an optical interferometer to process the reflected probe light pulses along two different optical paths to generate different optical output signals from the reflected probe light pulses along different optical paths, and optical detectors to receive the optical output signals from the optical interferometer; and a device controller coupled to the optical detection unit to extract information on spatial distribution of acoustic—or vibration—or strain-dependent characteristics as a function of distance along the fiber link under test.
