C/C-SiC复合材料是由多个微组分组成的，其性能往往不能精确表征。这种知识的缺乏使得难以使用多尺度数值模拟，需要可靠的微观数据来估计单个微观参数对复合材料宏观性能的影响。由于要表征的物质体积小，常规方法通常是不实用的，而调制光热技术是唯一方便的技术，该技术在微米至毫米的尺度上无任何接触地操作。
The C/C-SiC composites are made of several micro-components, whose properties are often not characterized precisely. Such a lack of knowledge makes difficult the use of multi-scale numerical simulations that require reliable microscopic data to estimate the influence of individual micro-parameters on the composite macroscopic properties. Because of the small volume of matter to be characterized, conventional methods are generally unpractical and modulated photothermal techniques, which operate without any contact at scales ranging from micrometers to millimeters, are the only convenient techniques.
