A Method of Enhancing the Sequence Image Using Infrared Thermal Wave Nondestructive Imaging Technology

Data mapping method which displaying the data files to infrared heat wave sequent images and an enhancing method for infrared heat wave sequent image of the defect were put forward. Those methods could enlarge the contrast of image and indicate the different change between the defect and the normal signals at different time. And it could be the basis to judge if there was defect.
