Fiber-based polarization-sensitive optical frequency domain imaging is more challenging than free-space implementations. Using multiple input states, fiber-based systems provide sample birefringence information with the benefit of a flexible sample arm but come at the cost of increased system and acquisition complexity, and either reduce acquisition speed or require increased acquisition bandwidth. Here we show that with the calibration of a single polarization state, fiber-based configurations can approach the conceptual simplicity of traditional free-space configurations. We remotely control the polarization state of the light incident at the sample using the eigenpolarization states of a wave plate as a reference, and determine the Jones matrix of the output fiber. We demonstrate this method for polarization-sensitive imaging of biological samples.
基于光纤的偏振敏感光学频域成像比自由空间实现方式更具挑战性。基于光纤的系统使用多个输入状态，在提供样品双折射信息的同时具备灵活样品臂的优势，但代价是系统和采集复杂度增加，要么降低采集速度，要么需要增加采集带宽。在此我们表明，通过对单个偏振态进行校准，基于光纤的配置可以接近传统自由空间配置的概念简单性。我们使用波片的本征偏振态作为参考，远程控制入射到样品的光的偏振态，并确定输出光纤的琼斯矩阵。我们展示了这种用于生物样品偏振敏感成像的方法。
