Abstract (en)
[origin: WO0016079A1] The aim of the invention is to provide a method which is non-destructive and which is not complicated in terms of the mathematics involved. To this end, one side of the laminar structure is irradiated with a short laser pulse, the temporal temperature profile caused by the laser pulse on the other side of the laminar structure is determined and the time taken to reach a given percentage of the maximum temperature is determined, this time being a measure of the quality of adhesion.
