Abstract: An optical fiber (FD) that can be used for measuring pressure is arranged as follows. The optical fiber (FD) comprises a core (CO) and a cladding (CL) surrounding and contacting the core (CO). A stress-applying arrangement (SE1, SE2), which is embedded in the cladding (CL), applies constant anisotropic stress on the core (CO). This causes the core (CO) to exhibit a deformation. A pressure conversion arrangement (HO1, H02), which is also embedded in the cladding (CL), converts isotropic external pressure applied to the optical fiber (FD) into pressure-dependent anisotropic stress applied to the core (CO). The pressure conversion arrangement (HO1, H02) is disposed with respect to the stress-applying arrangement (SE1, SE2) so that the pressure-dependent anisotropic stress enhances the deformation of the core (CO) caused by the constant anisotropic stress.

Abstract: A load and stress of a tensioner may be determined from the change in the strain of the tensioner. The strain of the tensioner may be detected by an optical device having a Fiber Bragg Grating (FBG) that is attached to the tensioner. An electrical signal may be generated in response to the detected change in the mechanical strain of the tensioner by processing the light reflected from an optical fiber coupled to the optical device. The electrical signal may be processed to calculate a load on the tensioner. The calculated load may be stored and analyzed, along with previously-stored values for the load, to determine the condition of the tensioner system, and whether the tensioner system requires maintenance.

Abstract: Mechanical parameters of an object subjected to a force or condition are measured. A curved portion of a multicore optical fiber is attached to the object, and the multicore optical fiber includes a center core and plural off-center cores. A distributed, optically-based sensing technique is used to obtain information at each of multiple points along the curved portion from multiple ones of the cores of the multicore optical fiber. A curvature associated with the fiber attached to the object is determined using the information obtained from multiple ones of the cores. Strain information is obtained for the center core without having to obtain strain information for the off-center cores. Mechanical parameters are determined based on the strain information obtained for the center core and the curvature information obtained from the multiple ones of the cores.
