摘要 本研究提出了一种旋转偏振显微成像方法。根据热解碳独特的双反射特性,设计了仅有一个检偏镜的显微图像采集系统;通过检偏镜的旋转,获取C/C复合材料在不同偏振角位置的单偏光图像;经过图像配准和图像融合,合成最大、最小反射率和双反射率映射图像。这种映射图像反映的信息是采用常规显微镜法不能观察到的,它直观地揭示了材料内部的微观结构特征,可以作为测定热解碳真实反射率的基础。本研究可为C/C复合材料微观结构分析以及相关特征参数测量提供理论依据和实现途径。

Abstract: A novel rotational polarized imaging method was developed for the microstructure analysis and the characterization parameter measurement of C/C composites in this work. An optical imaging system with a rotatable analyzer in the incident light path was established according to the bireflectance property of pyrocarbon. The micrographs of the polished C/C composite by the single-polarized light were collected at each analyzer position. The maps of maximum reflectance, minimum reflectance and bireflectance were obtainable from the ordered polarization images by the image registration and mergence methods. The maps were unique in that they show fields of view that cannot be seen by normal viewing in the microscope. The microstructure of C/C composites can be perfectly revealed in the integrated image, from which the true reflectance of pyrocarbon can be evaluated.
