Using multiphoton microscopy, we can image the tissue with sub-cellular resolution at depths down to 1.5 mm. Beyond this reach, the light must be delivered to the target region by optical relay elements inserted into the tissue the endoscopes. Focusing light through a step-index multimode optical fibre (MMF) using wave-front control enables minimally-invasive endoscopy. With fibre micro-endoscopes, we can reach any depth with negligible tissue disruption and keep the resolution below 1 micrometre, sufficient for in vivo microscopy. We designed a novel custom-terminated multimode fibre probe. This work will focus on optical fibre probe manufacturing methods (etching, polishing and coating) and their impact on imaging quality.
