Nondestructive Characterization of the Thermal Diffusivity of Poor Conductors by a Low Cost, Flash Technique
Numerous techniques and approaches exist for the determination of the thermal diffusivity through the thickness of materials. These include techniques based on photothermal radiometry, the detection of the acoustic wave excited by the heating beam, and the ‘mirage’ effect. These techniques typically incorporate a high power laser or an infrared camera, items that are relative expensive and not generally available in small-scale material evaluation facilities.
