Description

We describe progress in the rapid, contactless and accurate measurement of thermal diffusivity of materials. The technique is based upon pulsed heating of a slab, using a geometric pattern, followed by observation of time-dependent heat flow on the opposite surface of the slab, using a fast infrared video camera to acquire the time evolution of the thermal shadows at various edges of the heating pattern.
