Flexible Multicore-Multimode Fiber Endoscope for Super-Resolution Imaging

A multimode fiber (MMF) is a promising platform for minimally invasive bioimaging [1]–[3]. The main challenge of MMF-based micro-endoscopy is that it requires high stability of a fiber during the measurements preventing many real-life applications. Multiple methods are proposed to overcome the multimode fiber deformation issue, unfortunately, they sacrifice fidelity and imaging speed.
