标准傅里叶域光学相干层析成像（FDOCT）存在自相关项，模糊了目标信息，降低了灵敏度和信噪比。通过利用所记录的干涉图的相位信息，可以去除那些自相关项并使测量范围加倍。然而，标准的相位恢复算法需要三到五个干涉图。我们提出了一种新的技术，显示所有功能的复杂FDOCT只有两个记录的干涉图。(C)2003年美国光学学会。
Standard Fourier-domain optical coherence tomography (FDOCT) suffer's 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.
