Abstract
A plurality of optical fibers is helically embedded in tubular installation layers on the outer circumferential surface of a shaped body having a circular cross section. A three-dimensional position of the shaped body after deformed produced by bend, torsion, or stretch due to external force is measured by utilizing frequency change or phase change of pulse laser light emitted into the optical fibers caused by Brillouin scattering and/or Rayleigh scattering occurring in the optical fiber deformed in accordance with the shaped body deformation.
