Estimation of the thermal diffusivity of solids based on ‘instantaneous velocimetry’ using an interferometer

A conceptually new approach is proposed to estimate the thermal diffusivity of optically transparent solids at ambient temperature based on the ‘position-dependent instantaneous velocity’ of isothermal surfaces using a self-reference interferometer. A new analytical model is proposed using the exact...
