Pulsed photothermal radiometry relies on the flash heating of a surface and the detection of the time dependence of the surface cooling by infrared radiometry. We show that this is useful as a nondestructive and noncontact technique to quantify the thermal conductivity of a subsurface epoxy bond underneath an opaque surface. The degree of curing of the epoxy can also be monitored.
