摘要:
A system (100) for detecting the presence of an anomaly (102) within a component (104) includes a motorized apparatus (402) configured to move around the component. The system also includes an excitation device (112) and a camera (114) mounted to the motorized apparatus. The excitation device is configured to emit an excitation signal (116) toward the component to cause the anomaly within the component to generate a detectable reactionary thermal signal (118) in response to the excitation signal. The camera is configured to capture thermal images (124) of the component. The thermal images include the detectable reactionary thermal signal and indicate the presence of the anomaly within the component. The system further includes a controller (110) communicatively coupled to the excitation device and the camera. The controller is configured to receive and analyze the thermal images to detect the presence of the anomaly within the component. The controller is configured to adjust one or more operating parameters of the system to affect a characteristic of the detectable reactionary signal based on the thermal images.
