ABSTRACT:
A system for detecting defects in paint coatings includes a temperature manipulation apparatus configured to change the temperature of a surface and a coating applied to the surface. The system may further include an infrared sensor for measuring the change in temperature (over time) of the surface and coating and a processor to compare the measured change in temperature of the surface and coating to an expected change of temperature (over time) in order to determine anomalies in the coatings. A self-referencing method of determining defects is also disclosed, wherein surrounding pixels are utilized as a reference in the detection process for calculating the change in temperature of each pixel. In addition, application of the inventive aspects to inspection of adhesion interfaces is also disclosed.
