  • System and method for evaluating a structure
    Patent number: 6595684
    Abstract: In a system (10) for evaluating a structure (20), the structure (20) has a predetermined baseline thermal signature. The system (10) includes a thermal source (30) located at least partially inside the structure (20). The thermal source (30) is operable to generate a predetermined amount of heat, which heats the structure (20). The system (10) also includes a detection device (40) that is operable to determine the temperature at various points of the structure (20). The system (10) further includes a computer (50) that is coupled to the detection device (40). The computer (50) is operable to generate a thermal signature of the structure (20) based on the temperature at the various points. The generated thermal signature of the structure (20) is compared to the baseline thermal signature of the structure (20) to determine whether anomalies exist in the structure (20).
