We present a polarization-sensitive spectral-domain optical-coherence-tomography system that is capable of retrieving, with a single camera, both retardation and optical axis orientation. The method is based on a differentiation between orthogonal polarization channels through spatial modulation introduced by an electro-optic modulator. Proof-of-principle measurements using a wave plate as a sample are provided, and results of the method for in vivo imaging of the birefringent structures within the human nail fold are presented. Furthermore, we demonstrate the capability of such systems to perform ultra-high-speed polarization-sensitive imaging at 100.000 A-scans/s.
我们提出了一种偏振敏感的光谱域光学相干层析成像系统，该系统能够通过电光调制器引入的空间调制在单个相机中同时获取延迟和光轴方向。该方法基于通过正交偏振通道之间的差分。提供了使用波片作为样品的原理验证测量结果，并展示了该方法用于人指甲褶皱内双折射结构的体内成像的结果。此外，我们证明了这种系统能够以 100,000A-scans/s 的超高速进行偏振敏感成像的能力。
