Abstract
The main disadvantage of the IR thermography method for detection of buried mines is the presence of plentiful false indications in a thermogram. This often makes the level of false alarm too high. In a single and raw thermogram it was possible to identify mine with a naked eye only in rather rare and very carefully chosen, circumstances. We stated, that more attention should be directed on recognizing time evolution of detected signals, the same as recognizing usefulness of concepts and methodologies used in Dynamic Quantitative IR Thermography and active Thermal NDT. This paper presents the time dependent aspects of phenomenology potential detection mechanisms of buried mines, the same as selected methodologies developed for Thermal NDT and Dynamic Quantitative IR Thermography research and industrial applications. Results of the first trials in application software specialized for typical dynamic QIRT problems are shown, too.
