Claim One:
1. A method for inspecting a component, the method comprising: inducing, by an inductive coil, an electrical current flow into the component; capturing, by an infrared (IR) camera, thermographic data of the component, wherein the thermographic data comprises at least a first set of frames corresponding to a first area of the component at a first time interval and a second set of frames corresponding to a second area of the component at a second time interval different from the first time interval; determining, by a processing unit, a first reference point in the thermographic data of the first set of frames based on a drop in temperature at a portion of the component, wherein the first reference point indicates that the portion of the component is blocked from the IR camera; determining, by the processing unit, a second reference point in the thermographic data of the second set of frames based on a drop in temperature at an another portion of the component, wherein the second reference point indicates that the another portion of the component is blocked from the IR camera; selecting, by the processing unit, a first sub-set of frames from the first set of frames, wherein the first sub-set of frames is selected within a first process period before the first reference point; selecting, by the processing unit, a second sub-set of frames from the second set of frames, wherein the second sub-set of frames is selected within a second process period before the second reference point; constructing, by the processing unit, a thermal image based on at least the first sub-set of frames and the second sub-set of frames corresponding to the component; and determining presence of a thermal signature in the thermal image, wherein the thermal signature is representative of a defect in the component.
