基于光纤的高速偏振敏感傅立叶域光学相干断层扫描 (PS-FD-OCT) 采用偏振调制方法在 840 nm 波长下开发。偏振的入射状态沿 B 扫描进行调制。该光谱仪配有一个偏振分束器和两个线速 CCD 相机，线速为 27.7 kHz。根据沿 B 扫描的空间频率的 0 阶和 1 阶，可以导出深度分辨的琼斯矩阵。由于沿 B 扫描的连续偏振调制会导致条纹冲蚀，因此将等效的离散偏振调制应用于生物测量。为了进行演示，测量了体外鸡胸肌、体内指垫和人类牙齿的体内龋齿病变。三维相位延迟图像显示了将该系统应用于生物和医学研究的潜力。 (c) 2006 年美国光学学会。
Fiber-based high-speed polarization-sensitive Fourier domain optical coherence tomography (PS-FD-OCT) is developed at 840 nm wavelengh using polarization modulation method. The incident state of polarization is modulated along B-scan. The spectrometer has a polarizing beamsplitter and two line-CCD cameras operated at a line rate of 27.7 kHz. From the 0th and 1st orders of the spatial frequencies along the B-scanning, a depth-resolved Jones matrix can be derived. Since continuous polarization modulation along B-scan causes fringe washout, equivalent discrete polarization modulation is applied to biological measurements. For the demonstration, an in vitro chicken breast muscle, an in vivo finger pad, and an in vivo caries lesion of a human tooth are measured. Three dimensional phase retardation images show the potentials for applying the system to biological and medical studies. (c) 2006 Optical Society of America.
