| Abstract: | Optical coherence tomography (OCT) is a noninvasive cross sectional imaging technique that uses a low coherence optical source to perform coherence domain reflectometry of tissue microstructure. On the basis of investigating the development and progress,the OCT system is set up with superluminescent diode ( SLD ) and a tunable mode locked Ti: Sapphire femtosecond pulse laser source. Some properties of our OCT system, lateral and longitude resolution, are tested and analyzed. Cross sectional images of some kinds of samples were obtained. |
