Abstract

In this paper the liquid thermal diffusivity measurement through pulsed photothermal deflection in a modified collinear configuration is presented and discussed. The condition that the pulsed beam is regarded as in the form of a Dirac delta function here is given out. Comparison between theory and experiment is also shown.
