The aim of this project is to develop an accurate analytical model of radiative transfer through porous ceramic thermal barrier coatings TBCs. In particular, the model is aimed at computation of the integrated optical path-length as a function of several basic parameters including bulk scatter and absorption coefficients. Further, the model will need to take into account the effects of interface reflections and a multilayer structure. Such a model is of interest for use in low coherence interferometry measurements also referred to as optical coherence tomography on TBCs, in particular those that have been infiltrated with molten silicates CMAS - calcium, magnesium, aluminum oxide silicates.
