Discussion on How to Achieve Comprehensive and Accurate Calibration of Infrared Thermal Imager
Based on the working principle of the infrared thermal imager,combined with some key parameters and calibration requirements of the thermal imager,this paper focuses on analyzing the influence of its technical param-eters on the metrological performance,and discusses how to accurately calibrate the temperature of the thermal ima-ger.At the same time,in order to comprehensively evaluate the metrological performance of the thermal imager,several new calibration parameters of the thermal imager are proposed,and their calibration methods and calibration steps are described.
