Laser lock-in thermography for thermal contact characterisation of surface layer

Lock-in thermography was applied to determine the thermal contact conductance of a W-layer (140μm) on a CFC-substrate. A lock-in thermography system together with a pulse repetition rate Nd:YAG laser (1064nm, 1–500Hz pulse repetition rate) for layer heating was applied for phase shift measurements o...
