光学相干断层扫描已成为医学成像的重要工具，并且越来越多地用于定量计量应用。因此，检测灵敏度受到高度重视。在本文中，我们介绍了一种新颖的后处理技术，用于对光学相干断层扫描数据集进行数字稳定和光谱平均，以提高检测灵敏度。当该算法应用于来自高速傅里叶域系统的数据时，我们展示了 18 dB 的灵敏度增益。
Optical coherence tomography has become an important tool for medical imaging and increasingly for quantitative metrological applications. As a consequence detection sensitivity is highly valued. In this paper, we introduce a novel post-processing technique for digitally stabilizing and spectrally averaging optical coherence tomography datasets in order to enhance detection sensitivity. We demonstrate sensitivity gains of 18 dB when the algorithm is applied to data from a high-speed Fourier domain system.
