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 $52\mathrm{kHz}$, for DC suppression of $73\mathrm{dB}$ and complex conjugate suppression of $35\mathrm{dB}$. Densely sampled (3000 A-scans/image, acquired at $4.3\text{\hspace{0.17em} images}∕\mathrm{s}$) full-depth in vivo images of optic nerve head show CCA suppression for most image reflections to the noise floor.
