Paper Abstract

In biomedical optics, Optical Coherence Tomography (OCT) is an emerging optical imaging modality during the last three decades. OCT can perform high resolution, cross-section imaging of the internal microstructure in biological tissues by measuring echoes of backscattered light. We have developed a broadband, high-resolution spectral domain OCT system whose central wavelength is 1300 nm with bandwidth ~400 nm. Theoretical axial resolution of the system is ~3.71 μm and experimentally we get ~5 μm in air. Furthermore, we will apply this system for nano-sensitive detection and visualization in varieties of biological tissues.
