| 摘要 |
A multi-core optical fiber pressure 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 arranged such that a pressure induced force will act on the multi-core fiber at said collocated position, affecting the light guiding cores in a different manner. In another exemplary embodiment, the optical fiber is configured to bend in response to pressure changes.
