ABSTRACT:
A method and apparatus for detecting, locating, isolating and controlling variations in the manufacturing process by transient thermography. A heat source imparts heat to a surface which is radiated in the infrared region. Infrared sensors are coupled to a processor which tracks the physical characteristics of the sample, and provides feedback to a central process controller to make adjustments to the manufacturing process.
