Abstract

Many application fields need information about the thermal properties of the used materials. Heat management is becoming very import for example in the building industries due to exploding energy costs, automobile industry or in the photonics and semiconducting industries as well. A lot of research and development has been done regarding the development of thermal diffusivity measurement methods. Recently, dynamic measurement methods, which are much faster than static ones are in progress. The paper relates to the optical, non-invasive method for measuring material thermal diffusion coefficient. Experimental results regarding the measurement of thermal diffusion coefficient of vitreous As-S materials are presented. The way to improve the sensibility is proposed and discussed.
