    An infrared blackbody radiator is a pivotal part of test and calibration equipment for an infrared system.To meet the requirements of minitypelight weight and highprecision for portable field test equipment of the infrared imagerwe designed the structurecontrol circuit as well as the software of blackbody radiator.The blackbody radiator componentsmall and highly efficientwas composed of redcopper radiant areathermoelectric cooler and thermal sink.The temperature acquisition precision of 0.0122 ℃ was realized by using the bridge for measuring temperature driven by the constant current.The conversion precision of 0.01 ℃ between the acquired voltage and the real temperature was achieved by using the indexing function of platinum resistance and the Newton iteration method.Test result shows that the emissivitytemperature control precision and the size of the IR blackbody radiator can meet the requirementand the infrared blackbody radiator has successful application effect.
