摘要

光学相干层析成像（OCT）中的色散失配通常通过物理或数字补偿来解决。在这项研究中，我们研究了色散对OCT检测灵敏度的影响，并比较了物理补偿和数字补偿在不同色散不匹配程度下的有效性。结果表明，虽然数字色散补偿可以有效地恢复检测灵敏度，但其效果受到色散失配严重程度的限制。超过一定阈值后，数字补偿不能完全恢复图像信息，导致图像质量下降。

Effectiveness of digital dispersion compensation in OCT.

Dispersion mismatch in optical coherence tomography (OCT) is typically addressed through either physical or digital compensation. In this study, we investigate the impact of dispersion on OCT detection sensitivity and compare the effectiveness of physical and digital compensation across varying degrees of dispersion mismatch. Our results demonstrate that while digital dispersion compensation can effectively restore detection sensitivity, its efficacy is constrained by the severity of the dispersion mismatch. Beyond a certain threshold, digital compensation fails to fully recover image information, leading to degradation in image quality.
