Abstract：Various types of deposited carbon textures can be identified by the appearance under optical microscopy with cross-polars.The extinction angle of the deposited carbon in C/C composite can be measured by rotating the analyzer.The problems encountered during the observation by polarized light microscopy are listed.The method to measure the extinction angle is also introduced.In addition,the recently research results on pyrocarbon anisotropy is briefly presented.
