Doppler optical coherence tomography (DOCT) allows simultaneous micrometer-scale resolution cross-sectional imaging of tissue structure and blood flow. We demonstrate a fiber-optic polarization-diversity-based differential phase contrast DOCT system as a method to perform self-referenced velocimetry in highly scattering media. Using this strategy, we reduced common-mode interferometer noise to <1 Hz and improved Doppler estimates in a scattering flow phantom by a factor of 5.
多普勒光学相干断层扫描(DOCT)能够同时对组织结构和血流进行微米级分辨率的横截面成像。我们展示了一种基于光纤偏振分集的差分相衬DOCT系统,作为在高散射介质中进行自参考测速的一种方法。采用这种策略,我们将共模干涉仪噪声降低到<1 Hz,并将散射流模型中的多普勒估计提高了5倍。
