Thermal diffusivity can be measured by analysing the pulse response of the rear-face or of the front-face using a single detector or an IR camera. For the front-face configuration a simple identification method is proposed in the case of significant heat losses. The method is based on original correlations established between the occurrence times and values of the first and second logarithmic derivatives obtained by the thermographic signal reconstruction (TSR) method. The intrinsic accuracy of the identified diffusivity is evaluated by numerical simulations and validated by the analysis of experimental thermograms. Guidelines are proposed to optimise the identification procedure.< Leer menos
