We demonstrate a fiber-based forward-imaging swept source OCT (SS-OCT) system using a two-axis silicon micromachined vertical comb-drive microscanner for high-speed, 3-D imaging of biological specimens. Higher signal-to-noise ratio of SS-OCT over traditional time-domain techniques, combined with low beam-steering loss of silver-coated scanning micromirrors with over 90% reflectivity, provide good imaging performance. Fast wavelength scanning of the laser source (scan rate: 20 kHz) over 110 nm… CONTINUE READING
