Abstract Share this page

Advances in evaluating pulse thermography data were achieved by applying traditional and advanced data processing techniques. The pulsed thermographic images acquired under less than ideal situations are enhanced to improve visualization for inspector evaluation through traditional spatial filtering techniques. A more advanced inverse filtering technique was developed to improve spatial resolution that employs a Thermal Modulation Transfer Function (TMTF) model to construct a thermal inverse filter. The filter reduces the blurring due to lateral diffusion in images of subsurface targets. Examples of traditional and the advanced filtering on composite and metal sample data are presented
