Paper Abstract

Multimode fiber (MMF) endoscopy offers high spatial resolution in an ultra-small form factor, yet several technical challenges remain to be addressed to realize practical MMF imaging. Here, we demonstrate a strategy for confocal reflectance imaging through MMF to improve contrast owing to optical sectioning and enable volumetric imaging. Instead of physically focusing the light into the sample, it uses a series of distinct illumination patterns obtained by varying the proximal coupling of the illumination. This alleviates the need for active wave-control and translates into a speed advantage critical for practical MMF imaging.
