Abstract: Aiming at low imaging speed of Timedomain optical coherence tomography (TDOCT), VC++ and Matlab mixed programming technology was employed to develop twodimensional Fourierdomain optical coherence tomography (2D FDOCT) system which could image the internal structure of samples rapidly. A 2D FDOCT system was developed to replace onedimensional FDOCT system. An array CCD camera drove by computer was used to acquire the interference data. NI dataacquisition card controlled by computer was utilized to drive the PZT to achieve the phase shift needed in the FDOCT system. For the sake of threedimensional imaging, a linear electric stage was drove to scan the samples. The results indicate that the developed Twodimensional FDOCT system is highly integrated. The developed control software is multiple functions with a friendly interface and it is convenient for software maintenance and upgrade. Compared with onedimensional FDOCT system, Twodimensional FDOCT system reduced the scanning time and therefore increased the imaging speed.
