摘要: 为了实现更大范围的辐射测量,研制了一套大口径低温黑体标定装置。该装置采用工质制冷技术,避免了大量液氮消耗;采用辐射面竖直放置,有利于红外测量设备标定使用;采取了双参数联动PID控制方案,实现了宽温区辐射体的高稳定性控温。该装置研制中使用了低温黑体的防结霜技术、低温黑体辐射定标温度修正技术、低温黑体校准技术等,为建立低温黑体辐射标准打下基础。

Abstract: A calibration device of low temperature blackbody with large aperture is developed in the need of measuring more ranges. This device adopts working medium refrigerating technology to avoid using large amount of liquid nitrogen. It adopts upright radiating plate to convenient for IR camera operation. It also adopts dual parameter linkage control to realize high accuracy temperature control in wide range. This device uses anti-frosting technology, temperature revision and correction technology to lay solid foundation for calibration standard establishment.
