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 9):
The method as in  claim 1 , comprising:\n prior to perform shape sensing, calibrating the multi-core fiber sensor by inducing fiber bending and twisting to the fiber cores of the multi-core fiber sensor and measuring the returned probe light, wherein the calibrating includes: maintaining the multi-core fiber sensor at an original shape without inducing any bending and twisting while directing the probe light into each of the different fiber cores of the multi-core fiber sensor to obtain first calibration electrical signals for the different fiber cores in the multi-core fiber sensor to represent an undisturbed sensor state while accounting for intrinsic fiber twist or bending; inducing a known bending without twisting to the multi-core fiber sensor while directing the probe light into each of the different fiber cores of the multi-core fiber sensor to obtain second calibration electrical signals for the different fiber cores in the multi-core fiber sensor to represent the known bending; inducing a known twisting without bending to the multi-core fiber sensor while directing the probe light into each of the different fiber cores of the multi-core fiber sensor to obtain third calibration electrical signals for the different fiber cores in the multi-core fiber sensor to represent the known twisting; and using information from the first calibration electrical signals indicating the intrinsic fiber twisting or bending without any applied bending to twisting, the second calibration electrical signals indicating the known bending without twisting and the third calibration electrical signals indicating the known twisting without bending to calibrate the electrical signals obtained in measuring a shape of an object.
