The patent discloses a method and a device to perform thermal diffusivity measurement on bulk materials using a modulated spot heating of the sample surface and measuring the surface temperature on the spot with an infrared detector at different modulation frequencies. Since the method is single sided and it can be performed on a bulk, it does not require the preparation of a sample. Furthermore it does not require a precise alignment nor a movement of the heating source nor of the infrared detector.

Abstract
The patent discloses a method and a device to perform thermal diffusivity measurement on bulk materials using a modulated spot heating of the sample surface and measuring the surface temperature on the spot with an infrared detector at different modulation frequencies. Since the method is single sided and it can be performed on a bulk, it does not require the preparation of a sample. Furthermore it does not require a precise alignment nor a movement of the heating source nor of the infrared detector.File in questo prodotto:
