Abstract
The spectral radiation of extended area blackbody source is widely used to provide a reference for absolute temperature in infrared test and calibration. Thus the temperature accuracy of extended area blackbody is a critical parameter to determine the performance of test and calibration system. The temperature of emissive surface is measured and controlled by Platinum resistance temperature sensor. A variety of techniques have been developed for improving the temperature accuracy of extended area blackbody. In order to overcome nonlinear error caused by the Platinum resistance temperature sensor, a calibration method based on two-point multi-section linear correction algorithm is proposed. The tests verify that the method enhances the calibration accuracy of temperature accuracy of extended area blackbody and satisfies the requirements of high precision tests on metrological quality.
