摘要
Microsized endoscopy is increasingly demanded in medical clinical diagnosis for imaging in small blood vessels or delicate organs. In this paper, we propose a 3D printed side-viewing microlens on fiber tip by using the femtosecond laser two-photon polymerization (TPP) method for optical coherence tomography (OCT) imaging applications. The printed microlens is only 210 μm in width and 270 μm in height, its measured lateral resolution is around 9.4 μm in air. It is demonstrated that the proposed microlens can easily profile the depth resolved inner structure of a homemade plastic pipe.
