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 21):
An optical fiber sensor for shape sensing, comprising:\n a probe light source to produce probe light; a fiber having a fiber core and engaged to an object to optically sense a shape change in the object that is experienced by the fiber core; an optical light coupling module configured to receive the probe light from the probe light source and to direct the probe light into the fiber core to produce returned probe light from the fiber core; an optical interferometer coupled to receive the returned probe light from the fiber core to produce an optical output; 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 associated with the shape change at the fiber core; and a sensor processor coupled to receive the electrical signal from the optical detector, the sensor processor configured to process the electrical signal to monitor a shape-related optical polarization evolution in the returned probe light from the fiber core to determine the shape change.
