Abstract

We demonstrate high-speed complex conjugate artifact (CCA) resolved imaging of human retina in vivo using spectral domain optical coherence tomography. This technique utilizes sinusoidal reference mirror modulation to implement high-speed integrating buckets acquisition and a quadrature projection reconstruction algorithm in postprocessing. This method is illustrated experimentally using sets of four integrating bucket phase scans, acquired at 52kHz, for DC suppression of 73dB and complex conjugate suppression of 35dB. Densely sampled (3000 A-scans/image, acquired at 4.3  imagess) full-depth in vivo images of optic nerve head show CCA suppression for most image reflections to the noise floor.
