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 22):
The sensor as in  claim 21 , wherein:\n the optical interferometer coupled to receive the returned probe light includes: a reference path coupled to receive a portion of the probe light from the probe light source without being directed to the fiber core as a reference light beam; a probe path coupled to receive the returned probe light from the fiber core; an optical coupler coupled to both the probe path to receive the returned probe light and the reference path to receive the reference light beam and to spatially overlap the returned probe light and the received reference light beam to produce an optical interference signal as the optical output.
