Real-time holographic lensless micro-endoscopy through flexible fibers via fiber bundle distal holography

This paper presents Fiber Bundle Distal Holography (FiDHo), a novel approach for bend-insensitive, coherence-gated, micro-endoscopic imaging using commercially available multi-core fibers (MCFs). By adding a partially reflecting mirror to the distal fiber tip, low-coherence full-field phase-shifting holography is enabled, achieving video-rate, diffraction-limited reflection imaging of amplitude and phase targets through dynamically bent fibers. This approach holds promise for label-free investigations of dynamic samples.
