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.
