Use of Matlab Package for External Local Calibration of IR Camera with Microbolometric FPA Detector

摘要

This work presents the method of improving the accuracy of temperature measurement results obtained by means of long-wave infrared camera equipped with focal plane array (FPA) detector. The typical accuracy of infrared cameras specified by their manufacturers amounts to ±2 K or ±2% of the measured value of temperature. Very often a better accuracy of the measurements is required, e.g. during the measurements of human body temperature. To improve the measurement accuracy an external local (in terms of temperature range) correction of obtained results on the basis of comparison measurement results of black body temperature and next with use of MATLAB package has been proposed.
