Metasurface Enhanced Lensless Endoscopy
We integrate a metasurface with a multicore fiber in a lensless two-photon endoscope. The fiber’s transmission matrix is measured using an SLM, and its phase corrections are transferred to the metasurface to enable beam focusing. Our ongoing work suggests that integrating tip-tilt scanning could eventually allow point-by-point image reconstruction, paving the way toward truly miniaturized endoscopic imaging.
