Abstract
A multi-core optical fiber sensor is described, which sensor includes an optical fiber having at least two cores, wherein the cores have collocated measurement portions, for example in-fiber interferometers or Bragg grating portions. In an exemplary embodiment, the fiber is provided with collocated measurement portions during fiberization to eliminate drift factors and to provide temperature corrected parameter measurement capabilities.
