Super-resolution imaging in a lumen

Abstract: In this presentation, we present recent progress on in vivo super resolution imaging based on single multimode fiber. Although super-resolution imaging enables subcellular imaging and leads breakthroughs in the fields of biology and life sciences, robust in vivo nano-endoscopy is challenging. Spatial-frequency tracking adaptive beacon combined with spatial frequency engineering was proposed to ensure KHz fast tracking high stable super-resolution multimode fiber endoscopy imaging. Sub-diffraction-limited resolution about 250 nm (λ/3NA) is achieved. Multimode fiber has been integrated in a white-light endoscopy (WLE) to achieve cross-scale in vivo imaging inside the lumen. The high resolution and robust observation in a minimally invasive manner will provide an exciting new modality to endoscopy with wide applications in basic biology and clinic research.
