The imaging speed of a time domain optical coherence tomography (OCT) system is limited by the speed of the moving mirror. As a solution to this problem an integrated-optics-based multiple-reference TD-OCT system is presented in this work. The reference and sample lights will be sequentially tapped out at multiple locations using electro-optically controlled switches. For the design considered here an axial resolution of 20 µm and a depth range of 1 mm at the central wavelength of 800 nm were aimed at. With this design the mechanical scanner will be completely eliminated and, thereby imaging speed will be significantly improved.
