A typical infrared (IR) thermographic system intended for active thermal/IR nondestructive testing includes a heat source, an IR imager and a computer. The software ensures acquisition and processing of IR image sequences to result in a binary map of defects or other image which is to be interpreted by a thermographer in order to meet inspection requirements. Typically, hardware developers supply a certain set of technical parameters of their units, such as heater power, imager temperature resolution, acquisition rate and a set of available data processing algorithms. The suggested approach allows optimization of inspection parameters if thermal and optical parameters of test materials are known.
