InfraRed Thermography (IRT) is one of the promising imaging modalities for non-destructive testing/non-invasive evaluation of a wide variety of industrial as well as bio-materials. IRT gained wide acceptance due to its inherent merits such as safe, remote, fast and easy to deploy in the field for testing and evaluation of various materials. Among the widely used IRT approaches, recently introduced pulse compression favorable excitation schemes have become popular due to their higher test sensitivity and resolution even with the usage of low peak power probing energy into the test material. This talk highlights various signal and image processing approaches especially for high resolution coded excitation schemes. Further the merits and limitations of these approaches will be discussed for subsurface feature visualization in various industrial and bio-materials.
