Standard Fourier-domain optical coherence tomography (FDOCT) suffers from the presence of autocorrelation terms that obscure the object information and degrade the sensitivity and signal-to-noise ratio. By exploiting the phase information of the recorded interferograms, it is possible to remove those autocorrelation terms and to double the measurement range. However, standard phase-retrieval algorithms need three to five interferograms. We present a novel technique that shows all the features of complex FDOCT with only two recorded interferograms.
标准傅里叶域光学相干断层扫描（FDOCT）存在自相关项，这些自相关项会模糊目标信息，降低灵敏度和信噪比。通过利用记录的干涉图的相位信息，可以去除那些自相关项并将测量范围加倍。然而，标准的相位恢复算法需要三到五幅干涉图。我们提出了一种新颖的技术，该技术仅用两幅记录的干涉图就能展现出复FDOCT的所有特征。
