鼻咽癌细胞后向偏振散射光谱研究

基于偏振门技术建立了一套后向偏振散射光谱测量系统。在系统中,入射光被调制成线偏振光,聚焦于样品表面,测量后向散射光中平行和垂直分量的差分光谱,再由测量值计算出偏振度光谱。并将该系统初步应用于区别不同时期的鼻咽癌细胞。结果表明:常规的光谱技术很难分辩出癌变过程中不同时期的鼻咽癌细胞,而后向偏振散射光谱术可以探测到显著差异。这可能为鼻咽癌的检测与研究提供一种新手段。

Research on Polarized Backscattering Spectra for Nasopharyngeal Carcinoma Cell

Based on polarization gating technique,an optic probe system for measuring polarized backscattering spectra of the tissue phantoms is presented in this paper.In the system,a linearly polarized,collimated visible light illuminate on the surface of the sample,backscattered components that are polarized parallel and perpendicular to the polarization of the illumination light are recorded by the fiber optic spectrometer.and applied it to differentiate nasopharyngeal carcinoma cells of different stages.Finally,t...
