Abstract
The criterion for distinguishing defects is investigated as a function of the ratio of the dimensions of the scanning spot and of the defect, taking into account the frequency characteristics of pyroelectric and photovoltaic receivers. The optimum ratio of these quantities which ensures maximum sensitivity in active thermal monitoring is established.
