AbstractAn optical coherence tomography (OCT) system based on a high-speed microelectromechanical system (MEMS) mirror is presented. This scanning mirror has high-speed performance because it was actuated by vertical comb drive. The size of mirror was 600 μm × 600 μm and the resonant frequencies were between 3.5 kHz to 8 kHz. In the test of scanner itself, it was operated linearly and scanned up to 30 degree angle. The MEMS mirror also provides 2-axis scanning while occupying a very small volume with extremely low power consumption. In our study, it was integrated with conventional fiber based OCT system. Via 2-axis lateral scanning, combined with an axial scan, a volume (2 mm × 2 mm × 1.4 mm) image of tissue, including a cancerous region, from a hamster cheek pouch was obtained. The axial and lateral resolution of images are 10 μm and about 20 μm respectively.
