我们描述了由于样本或探测光束运动而在谱域光学相干断层扫描 (SD-OCT) 和光频域成像 (OFDI) 中可能出现的伪影的理论和实验研究结果。虽然 SD-OCT 和 OFDI 基于相似的光谱干涉原理，但由于信号采集方法不同，运动效应的细节有很大不同。这些结果提供了对信号衰落、空间失真和模糊等运动伪影的理解，并强调了生物医学应用中快速图像采集的需求。 (C) 2004 年美国光学学会。
We describe results of theoretical and experimental investigations of artifacts that can arise in spectral-domain optical coherence tomography (SD-OCT) and optical frequency domain imaging (OFDI) as a result of sample or probe beam motion. While SD-OCT and OFDI are based on similar spectral interferometric principles, the specifics of motion effects are quite different because of distinct signal acquisition methods. These results provide an understanding of motion artifacts such as signal fading, spatial distortion and blurring, and emphasize the need for fast image acquisition in biomedical applications.
