Figure 2 | Three-dimensional deformation encoding using misplaced orthogonal eccentric scatterers. The MOES array converts directional bending information into distinct scattering signatures. When the fiber bends along different directions, the optical mode shifts within the core, producing characteristic changes in the Rayleigh scattering intensity of individual eccentric scatterers. These direction-dependent responses provide the basis for simultaneously retrieving local curvature and bending orientation, enabling three-dimensional shape reconstruction from a single optical fiber.
