A thermal detection technique using an infrared radiometer was discussed and applied to the detection of the internal heterogeneous spatial position in materials. The internal heterogeneous space represents a cavity, an inclusion and a separation of materials. To maintain and manage various structures, their positions must be analyzed. Therefore, in this study, the transient temperature distribution above internal flaws was measured. Solar energy and lump energy were used to realize nonsteady temperature field on the surface of materials within an internal heterogeneous space and those temperature fields were estimated experimentally. Moreover, we certified the temperature field using the proposed model based on experimental results. The detection limit of the thermal detection technique was also discussed simultaneously.
