Paper Abstract

One of the most crucial limitations of quantitative thermography is the fact that, besides true object temperature, many complicated factors are involved in the formation of thermographic image . In many applications, complete knowledge about uncertainties which make some contributions to apparent temperature of an object is usually not available and reasonable assumptions are necessary. In this study, a calibration method of quantitative thermographic image has been developed under the assumptions; 1) object is radiometrically gray, 2) optical pathway attenuation and ambient irradiance is negl igible, 3) imager response to incident radiation flux is linear. The proposed method was tested on the heating pattern study of microwave antenna which is applied to a tissue phantom and was found to provide accurate temperature map.
