Abstract

This paper contains inspection results for a carbon epoxy plastic reference specimen with Teflon TM inserts. A long-pulse heating technique and AGEMA-900 IR imager have been used. Results are presented as a set of twenty-two images including a source image, normalized image, timegram, depthgram, tomogram presented as B&W and color hard-copies, as well as live images on a color monitor. This set of data has been exhibited to operators (experts or not) together with the set of rules for detecting defects. Obtained data are processed statistically and compared with true defect locations. The Tanimoto criterion is used for data comparison. Recommendations on the best image processing technique, as well as on the best form of data presentation, are given.
