| Zusammenfassung | One of the important areas of applications of commercial thermal imagers is non-destructive thermal testing. An analysis of two standards published by the American Society for Testing Materials describing measurement procedures of the Minimum Resolvable Temperature Difference (MRTD) and the Minimum Detectable Temperature Difference (MDTD) was made in this paper. It was shown that in case of modern thermal imagers, the measurement results of these parameters carried out according to the ASTM recommendations can be unreliable. Proposals to update the standards and to enable accurate measurement of the parameters mentioned above are presented. A laboratory setup tor measurement of the MRTD and the MDTD that fulfils requirements of the proposals is described. Measurement results of the parameters for a modern commercial imager according to updated procedures are presented. |
