CALIBRATION METHODS OF INFRARED SPECTRUM RADIOMETER AT VARIOUS TEMPERATURES AND BACKGROUND TEMPERATURE ADJUSTMENT
红外光谱仪多点定标方法及环境温度校正

In calibration of a infrared spectrum radiometer, we calibrate an infrared radiometer by measuring on various temperatures of the blackbody in order to reduce error. For the radiometer measuring weak radiation, the background temperature has unavoidable effect on calibration. The methods of calibration by measuring the standard blackbody at different temperature was discussed. The experimentation results were analysed, and the effect of the background temperature on the calibration result was given.
