The optic axis of birefringent samples indicates the direction of optical anisotropy, which should be described in three-dimensional (3-D) space. We present a method to quantify the complete 3-D optic axis orientation calculated from in-plane optic axis measurements from a polarization-sensitive optical coherence tomography system. The in-plane axis orientations with different illumination angles allow the calculation of the necessary polar angle. The method then provides the information to produce the actual birefringence. The method and results from a biological sample are presented.
双折射样品的光轴表示各向异性光的方向，应该在三维（3-D）空间中进行描述。我们提出了一种从偏振敏感光相干断层扫描系统的面内光轴测量中计算完整 3-D 光轴方向的方法。不同照明角度的面内轴方向允许计算必要的极角。然后，该方法提供了产生实际双折射的信息。介绍了一种生物样本的方法和结果。
