介绍了一种消除超快光谱域光学相干层析成像（SOCT）中自相关伪影的简单方法，该方法使用单个B扫描内光谱的系综平均值作为背景信号，然后在执行fft之前从该B扫描内的所有A扫描中减去该伪影。这是一帧一帧不断更新的。该方法在体积速率（c模式）SOCT系统上进行了测试，以8秒的体积速率在体内对人体指尖进行成像。
A simple method is introduced to eliminate the autocorrelation artefacts in ultrafast spectral domain optical coherence tomography (SOCT) by use of the ensemble average of spectra within an individual B scan as the background signal, and then subtracting this from all the A scans within that B scan before performing the FFTs. This is updated continuously frame by frame. The method is tested on a volume-rate (C-mode) SOCT system to image the human fingertip in vivo with a volume rate at 8 s.
