Title:
CABLE, CABLE SHAPE SENSING SYSTEM, SENSING SYSTEM, AND METHOD FOR SENSING CABLE SHAPE
Document Type and Number:
WIPO Patent Application WO/2020/027223
Kind Code:
A1
Abstract:
A cable includes a plurality of optical fiber cores, and includes at least one optical fiber line having at least one optical fiber core, wherein the optical fiber lines are secured at a plurality of locations in the longitudinal direction of the cable in such a way that positional displacement is essentially prevented in the radial direction of the cable. The cable is configured using a plurality of structural materials including a transmission line, and the optical fiber line may be secured to at least one of the plurality of structural materials at a plurality of locations in the longitudinal direction.
