  • Title: Real-time quadrature projection complex conjugate resolved Fourier domain optical coherence tomography.
    Author: Sarunic MV, Applegate BE, Izatt JA.
    Journal: Opt Lett; 2006 Aug 15; 31(16):2426-8. PubMed ID: 16880844.
    Abstract:
    We present a novel algorithm for full-range imaging by suppression of the complex conjugate artifact in phase-shifting Fourier domain optical coherence tomography. This technique utilizes the projection of multiple phase-shifted interferograms onto an orthogonal basis set to reconstruct the complex interferogram. Full-range imaging with >30 dB suppression of the symmetric artifact is demonstrated using a 3 x 3 fiber coupler swept source OCT system, providing a depth range of 6.6mm with -8 dB roll-off in sensitivity at the depth boundaries relative to DC. Real-time display of full-range images of the anterior segment of the human eye acquired in vivo at a line rate of 6.67 kHz are presented.
