Abstract

A fiber based dual channel phase-sensitive optical low coherence tomography system is proposed for birefringence imaging neural tissues. The system measures relative optical path length differences between the orthogonal modes of the polarization-maintaining fiber in highly scattering media with high lateral and longitudinal spatial resolution. Because of the ability of detecting ultra-small changes in refractive index, system has uses in many bio-medical optical imaging applications such as monitoring cell and tissue dynamics, imaging of phase objects, and functional studies.
用于神经双折射成像的光纤相敏光学低相干反射计
提出了一种基于光纤的双通道相敏光学低相干层析成像系统,用于神经组织双折射成像。该系统测量保偏光纤在高散射介质中具有高横向和纵向空间分辨率的正交模之间的相对光程长度差。由于能够检测折射率的超微小变化,该系统在许多生物医学光学成像应用中得到了应用,如监测细胞和组织动力学、相位物体成像和功能研究。
