Figure 1 | Concept and fabrication of the MOES-based single-fiber 3D shape sensor. Researchers inscribed an array of misplaced orthogonal eccentric scatterers (MOESs) inside a standard single-mode optical fiber using femtosecond laser direct writing. The engineered scattering structure encodes directional bending information, enabling high-resolution three-dimensional shape reconstruction using a single optical fiber and a single interrogation channel.
