Thermal wave method - limits and potentialities of active thermography in biology and medicine

In biology and medicine active thermography methods can be used for measuring skin thickness, inflammation regions, density of tissues, blood flow, etc. We present the basis and preliminary application of lock-in and pulse thermography for nondestructive testing (NDT). 3D modelling is presented to confirm usefulness of simple analytical solutions, and to set up the experiments. As an example, the thickness of thin film coatings is briefly described.
