Abstract

Conventional endoscopic probes have a field-of-view (FOV) limited by the aperture size, hindering imaging of larger areas. We propose a non-contact approach combined with a non-telecentric design expanding the FOV to several times the probe diameter, which enables to capture the entire region of interest. Our implementation utilizes 3D-printed micro-lenses fabricated via two-photon polymerization, allowing precise control of lens parameters and a simplified integration onto a fiber tip resulting in a compact OCT system with expanded FOV in the cm-scale, surpassing conventional probe limitations.
