Abstract:
This patent document discloses fiber sensing techniques and devices for shape monitoring by using single- and multi-core optical fiber implementations and optical interferometry. Implementations can be made based on coherent optical time domain reflectometry (OTDR) or optical frequency domain reflectometry (OFDR).

Claim (Index 10):
An optical fiber sensor for shape sensing, comprising:\n a probe light source to produce probe light; different fiber cores that are displaced from one another and are engaged to an object to optically sense a shape change in the object that is experienced by the different fiber cores; an optical light coupling module configured to receive the probe light from the probe light source and to direct the probe light into the single-core sensor or different fiber cores in the multi-core fiber sensor to produce returned probe light from the different fiber cores of the multi-core fiber sensor; an optical interferometer coupled to receive the returned probe light from each of the different fiber cores of the multi-core fiber sensor to produce an optical output for a corresponding fiber core in the multi-core fiber sensor; an optical detector coupled to receive output light from the optical interferometer and operable to convert the optical output from the optical interferometer into an electrical signal that carries information on a local change shape experienced at a corresponding fiber core in the multi-core fiber sensor; and a sensor processor coupled to receive the electrical signals for different corresponding fiber cores in the multi-core fiber sensor from the optical detector, the sensor processor configured to process the electrical signals to monitor a shape-related optical polarization evolution in the returned probe light from each fiber core of the multi-core fiber sensor to determine the shape change from the electrical signals for different corresponding fiber cores in the multi-core fiber sensor.
