我们从理论和实验上证明，相位延迟和相对光轴方向的样品可以计算没有事先知道的相位调制幅度的实际值时，使用基于连续偏振调制的偏振敏感的光学相干层析成像系统（CPM-PS-OCT）。我们还表明，样本琼斯矩阵可以计算在任何值的相位调制幅度在一个合理的范围内，取决于系统的有效信噪比。通过简化偏振调制器驱动仪器并消除其校准程序，这对于临床系统的开发具有根本重要性。这是验证的四分之三波片和马肌腱样品的测量基于光纤的扫频源CPM-PS-OCT系统。
We demonstrate theoretically and experimentally that the phase retardance and relative optic-axis orientation of a sample can be calculated without prior knowledge of the actual value of the phase modulation amplitude when using a polarization-sensitive optical coherence tomography system based on continuous polarization modulation (CPM-PS-OCT). We also demonstrate that the sample Jones matrix can be calculated at any values of the phase modulation amplitude in a reasonable range depending on the system effective signal-to-noise ratio. This has fundamental importance for the development of clinical systems by simplifying the polarization modulator drive instrumentation and eliminating its calibration procedure. This was validated on measurements of a three-quarter waveplate and an equine tendon sample by a fiber-based swept-source CPM-PS-OCT system.
