Description
Xu and co-authors build, in 2026, a Janus metafiber system that gives fiber-bundle endoscopes both full-color 2D vision and 3D depth sensing in a single round trip of light. Fiber bundles gather intensity images but not depth. A quadratic-phase metasurface in the bundle, plus flipping the light path between forward and reverse modes, lets one setup do passive visible imaging and active depth sensing alternately.
The depth mode showed a 60-degree field of view with beam spread under 2 degrees, about 1.5 degrees in the refined tests, and depth accuracy better than 2 centimeters. Time-division capture, alternating single-wavelength array scanning with polychromatic illumination, kept the two channels apart and preserved image quality under noise. Combining data streams produced depth-resolved color images with edge detection. The authors target real-time medical diagnostics, LiDAR, and inspection inside engines and pipelines.
