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.
我们描述了由于样本或探测光束运动,在光谱域光学相干断层扫描(SD - OCT)和光学频域成像(OFDI)中可能出现的伪像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,运动效应的具体情况有很大差异。这些结果有助于理解诸如信号衰减、空间畸变和模糊等运动伪像,并强调了生物医学应用中快速图像采集的必要性。
