Modeling of the flash thermography process typically requires a priori knowledge of the thermophysical properties of the sample and likely defect mechanisms, as well as the amount of energy used to excite the sample. Often, this information is not re

Pulsed thermography has generally been used to identify, and in some cases, measure the depth of subsurface defects. In general, quantitative analysis of pulsed thermographic data has required the presence of a reference sample or region in the field

A common approach to characterizing the performance of Thermographie Systems for Nondestructive Testing (TNDT) employs calibrated flat bottom hole samples, in which holes of different depths and diameters are milled into the back side of a plate of a

Although pulsed thermography has been demonstrated as a means of detecting subsurface defects in a wide range of materials, quantification of defect size and depth has only been possible using high performance IR cameras, often operating at high fram

The video image of a geometrically simple target may appear to be complex if some component of the target is periodically varying at a frequency greater than the video frame rate. The presence of aliasing at above-frame-rate frequencies has hindered

Using an exact, three-dimensional, Green's function solution to the thermoelastic equations in semi-infinite solid, we have calculated the relative generation efficiencies of thermal waves, longitudinal acoustic waves and transverse acoustic waves in
