摘　　要：低温辐射计是迄今为止国际上公认最精确的光辐射功率测量系统,基于探测器的光辐射量值是可溯源的基本量。为验证不同实验室间的低温辐射计测量量值的一致性,由中国计量科学研究院作为主导实验室组织了此次低温辐射计比对,参比实验室包括中国电子科技集团第四十一研究所与西安应用光学研究所。介绍了比对的基本情况与技术方案,分析了比对结果。比对结果表明,各参比实验室相对于比对参考值的测量偏差在±0.02%之内;尽管各实验室使用的低温辐射计的类型不同以及装置存在差异,比对结果证明了各实验室低温辐射计测量的量值具有较好的一致性。Cryogenic radiometer is by far the most accurate measurement system of optical radiant power,which is the fundamental quantity of detector based radiometry.In order to verify the consistency of the measurement values among different laboratories,a measurement comparison of cryogenic radiometers was organized by National Institute of Metrology as pilot laboratory,participating laboratories include the 41st Research Institute of China Electronics Technology Group Corporation and Xi an Institute of Applied Optics.The comparison method,transfer standard and measurement facilities are presented,and the comparison results are analyzed.The comparison results show that the deviation of each laboratory relative to the reference value is within±0.02%,and the comparison results prove the consistency of scales realized from different types of cryogenic radiometers in each laboratory.
