Abstract

Preclinical studies and clinical diagnostics increasingly rely on optical techniques to visualize internal organs. Miniaturised catheters or endoscopes are necessary for imaging small and/or delicate arteries. However, current lens fabrication methods limit the performance of these ultrathin devices, resulting in a poor combination of resolution, depth of focus and multimodal imaging capability. This talk will introduce our latest research to address these combined challenges. In particular, we have utilized 3D micro-printing technology to fabricate freeform optics directly onto an optical fiber to achieve freeform designs for aberration-corrected optical coherence tomography (OCT) and to enable highly-sensitive multimodal fluorescence+OCT imaging in vivo.
