A review of infrared methods used for non-destructive testing of material defects is presented. Some experimental studies with the long wavelength IR camera are carried out when the pulse heating is used. Then the thorough theoretical analysis of the defect detectability with the use of the pulse thermography is performed. A sample with a two-dimensional defect with a rectangular cross-section is considered. Influence of different way of sample heating on thermal contrast is investigated for two materials with widely varying thermal properties.
