    High-speed full-range spectral-domain correlation mapping optical coherence tomography

    We present a full range spectral-domain correlation mapping optical coherence tomography (cm-OCT) method to obtain complex conjugate free, full-range correlation mapping angiography. The mirror image elimination is based on linear phase modulation of B-frames by introducing a slight off-set of the probe beam with respect to the lateral scanning fast mirror’s pivot axis. An algorithm that exploits Hilbert transform to obtain complex-conjugate free image in conjunction with the cm-OCT algorithm is used to obtain full-range imaging of microcirculation within tissue beds in vivo. The proposed system is based on a high speed spectrometer at 92kHz with a modified scanning ...
