Abstract	Some infrared sensing techniques for the industrial quality control of composite or stratified materials are described. The surface of the material is heated, typically by a coherent or incoherent light source, and the surface temperature evolution is monitored either by a single-spot infrared detector or by an infrared camera. Subsurface thermal discontinuities are detected by an analysis of the recorded signal. Signal-processing techniques using reference-subtraction either in the space- or in the time-domain are described which are particularly well-suited to the industrial inspection environment. Experimental results obtained with aluminum-plastics, aluminum-aluminum, and graphite--epoxy laminates are described
