Utility
One or More Fiber Optic Sensors Locally Bonded with a Flexible Filament Structure
6 Oct 22
An apparatus comprises a flexible filament structure, and a fiber optic sensor with a buffer material that locally bonds the fiber optic sensor to the flexible filament structure to create a bond between the fiber optic sensor and the flexible filament structure to transfer strain from the flexible filament structure to the fiber optic sensor to allow the fiber optic sensor to detect strain on the flexible filament structure while maintaining flexibility in the flexible filament structure.

Utility
Distributed Fiber Optic Acoustic Sensor
16 Dec 20
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.
