We present the evaluation of possible quantitative applications of the TSR (thermographic signal reconstruction) technique in the simple case of the adiabatic homogeneous plate with the application of the measurement of thickness or diffusivity. Theoretical and experimental analysis of the identification is achieved, leading to recommendations in view of obtaining a precise and reliable evaluation of these parameters. In particular, the use of the first logarithmic derivative of the thermogram is recommended instead of the second logarithmic derivative. The method when applied to homogeneous, constant-thickness and quasi adiabatic samples allows to consider the front-face measurement as a possible flash diffusivity technique with an accuracy comparable to that of the classical rear-face diffusivity method of Parker.
