摘　　要：在比较国际上基于低温辐射计的红外辐射定标技术的基础上,提出了以红外光源结合单色仪为辐射源,及以腔式热电堆探测器和低温辐射计为标准探测器的红外辐射定标方案。介绍了其结构和工作原理并给出了初步的定标结果。After comparing different infrared calibration methods based on cryogenic radiometer, We propose an infrared calibration method based on cryogenic radiometer using infrared source in combination with a monochromator as radiation source,cavity thermopiles detector and cryogenic radiometer as primary standard detectors. We present the working principle and a schematic description of the new facility. A status report is also given on the development of this facility.
