Abstract

See full text

A sensor fiber for the detection of changes of temperature, bending, and/or torsion includes a multicore optical waveguide with a fiber Bragg grating (FBG) structure. One embodiment contains at least two FBG cores and a surrounding cladding. The sensor fiber is characterized by one or more distinction and orientation means which produce a marker zone to assign and label each individual FBG core.
