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 1):
A method for monitoring a shape by using a fiber sensor having different fiber cores that are displaced from one another for shape sensing, comprising:\n directing probe light into the different fiber cores in the multi-core fiber sensor to produce returned probe light from each of the different fiber cores of the multi-core fiber sensor; directing the returned probe light from each of the different fiber cores of the multi-core fiber sensor into an optical interferometer to produce an optical output for a corresponding fiber core in the multi-core fiber sensor; operating an optical detector to convert the optical output from the optical interferometer into an electrical signal that carries information on a local shape change at a corresponding fiber core in the multi-core fiber sensor; and processing the electrical signals for different corresponding fiber cores in the multi-core fiber sensor 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.
