Abstract
A method and system for determining thermal diffusivity and porosity of an article are provided. The method comprises heating a surface of the article, capturing image data corresponding to an evolution of lateral heat flow from the surface of the article, applying a thermal time of flight analysis on the image data and determining thermal diffusivity and porosity values of the article using the thermal time of flight analysis for the lateral heat flow.
