Until recently, thermography was limited to a secondary, qualitative role in airfoil QA. However, advances in the technology have given rise to thermographic QA systems that are capable of replacing traditional technologies.

Physics-based approach drives growth of modern thermographic NDT applications.

Thermography is a well-established technique for predictive and preventative maintenance (P/PM), where the inspector uses the infrared (IR) camera in a passive mode to measure the steady state surface temperature of a component during its normal operation.

Modern pulsed thermography systems offer unprecedented speed, sensitivity and ease of use.
