我们提出并演示了一种基于改进的电子锁相环的新型检测技术，用于多普勒光学相干断层扫描。与传统的光学相干断层扫描相比，该技术允许在较宽的速度范围内对混浊介质进行实时同步反射率和连续、双向速度测绘，并且灵敏度损失最小，这是相对于当前后处理和离散并行检测技术的重大进步。
We propose and demonstrate a novel detection technique, based on a modified electronic phase-locked loop, for Doppler optical coherence tomography. The technique permits real-time simultaneous reflectivity and continuous, bidirectional velocity mapping in turbid media over a wide velocity range with minimal sensitivity penalty compared with conventional optical coherence tomography, which is a major advance over current postprocessing and discrete parallel detection techniques.
