Paper Abstract

We present a high-speed full range complex spectral optical coherence tomography system, which achieves an A-scan rate of 20000 depth profiles per second. By inserting a phase modulator into the reference arm and recording of every other spectrum with a 90∞phase shift (introduced by the phase modulator) we are able to distinguish between negative and positive optical path differences. A modified two-frame algorithm eliminates the problem of suppressing symmetric structure terms in the final image. To demonstrate the performance of our system we present images of the human anterior chamber in vivo.
