The intensity of the emitted infrared radiation is especially influenced by material characteristics. Due to component imperfections like blow holes or cracks the heat flow is affected. Depending on the investigation method (reflection or irradiation, see Figure 2) imperfections lead to heat sources or sinks on the surface. This fact is used for volumetric failure detection.
