Abstract
A thermographic inspection system includes a heat source configured to be removably attached to an exterior surface of an object. A thermal imaging device obtains a thermal image of the object, and an analyzing device determines a location of a defect in the object based on the thermal image.
Claims20
A thermographic inspection system comprising:
- a heat source configured to be removably attached to an exterior surface of an object;
- a thermal imaging device that obtains a thermal image of the heat source;
- and
- an analyzing device that determines a location of a defect in the object based on the thermal image,
- wherein the heat source is disposed between the object and the thermal imaging device, and
- wherein the analyzing device determines a surface temperature of the heat source to determine the location of the defect in the object when the heat source is attached to the object.

A method of inspecting an object, comprising:
- removably attaching a heat source to an exterior surface of an object;
- energizing the heat source to generate heat;
- transmitting the heat to the exterior surface of the object by thermal conduction;
- acquiring a thermal image of an exterior surface of the heat source when the heat source is attached to the exterior surface of the object;
- and
- determining a location of a defect in the object based on the thermal image.
3 more elements
A method of inspecting an object comprising:
- removably attaching a heat source to an exterior surface of an object;
- injecting heat into the object from the heat source through the exterior surface of the object by thermal conduction;
- acquiring a thermal image of an exterior surface of the heat source when the heat source is attached to the exterior surface of the object;
- and
- determining a location of a defect in the object based on the thermal image.
