Abstract

We demonstrate a compact all-fiber probe for a common path optical coherence tomography (CPOCT) system. By forming a focusing lens directly on the tip of an optical fiber, a compact fiber probe could be constructed. The microlens is produced by forming a droplet with UV-curing adhesive on the cleaved tip of multimode fiber. It fulfills two functions acting as both the reference plane and the imaging lens. To simultaneously achieve a relative long working distance and a good lateral resolution, we employed a large core size multimode fiber. A working distance of 280μm, and a transverse resolution of 14μm were achieved with the implemented MMF lensed fiber. The performance of the CPOCT system with the proposed MMF lensed fiber is presented by showing the OCT images of an onion tissue as biological sample.
