Abstract
Conventional optical coherence tomography (OCT) systems generally have a limited imaging range within a depth of only 1-2 mm and suffers from unwanted noise such as speckle, ghost or mirror noise. To overcome these limitations, we developed a motorized-stage-based OCT system with an extended imaging range, using a common-path Fourier-domain optical coherence tomography (CP-FD-OCT) configuration. Using this OCT systems, OCT image was obtained from an onion, and their subsurface structure were observed. The result showed that the OCT images obtained using our motorized-stage-based system had a significantly extended imaging range due to its real-time accurate depth tracking. Consequently, the devised CP-FD-OCT systems and algorithms have good potential for the further development of endoscopic OCT for microsurgery.
