Pulsed thermographic method refers to the nondestructive testing of parts, materials or systems through monitoring the thermal patterns at the object''s surface. However, it takes lots of memories and produces more noises than expected to work through this method. Two solutions are proposed here to solve this problem. One is using the thermography signal reconstruction method via polynomial fitting way to reshape the raw images, by which the memories needed can be save up to about 70%, the other is using fuzzy expert system to further enhance image contrast and to suppress image noises. Three types of defects (Teflon, Polyester and paper) are buried into the carbon fiber composite plates to simulate material defects, of which polyester and paper flaws are usually residual in the bad processes of carbon fiber composite and Teflon defect behaves as material delamination. Take paper flaw as an example, using the presents study, the image contrast can enhance 1.7 and 1.4 times respectively for the numerical simulation and experimental techniques. The proposed method proves its effectiveness both for simulation and experimental works.
