提出了一种基于光纤的多功能琼斯矩阵扫描源光学相干层析成像(SS-OCT)系统，用于多普勒和偏振成像。基于两正交偏振态独立延迟的入射偏振复用器和偏振分集检测，实现了不使用电光调制器等有源元件的琼斯矩阵测量。除了偏振灵敏度外，该系统还可以测量多普勒血流，而不需要额外的硬件来进行相位稳定SS-OCT检测。通过对一块第八波片的测试，验证了该偏振检测的准确性。活体测量视网膜的视神经头。同时对详细的血管结构和双折射结构进行了研究。(C)2012年美国光学学会
We present a fiber based multifunctional Jones matrix swept source optical coherence tomography (SS-OCT) system for Doppler and polarization imaging. Jones matrix measurement without using active components such as electro-optic modulators is realized by incident polarization multiplexing based on independent delay of two orthogonal polarization states and polarization diversity detection. In addition to polarization sensitivity, this system measures Doppler flow without extra hardware for phase stabilized SS-OCT detection. An eighth-wave plate was measured to demonstrate the polarization detection accuracy. The optic nerve head of a retina was measured in vivo. Detailed vasculature and birefringent structures were investigated simultaneously. (C) 2012 Optical Society of America
