【摘要】：在地外太阳光谱辐照度测量和大气定量遥感等项研究的推动下,近二、三十年,国际上光谱辐射计量技术发展十分迅速。基于先进的高温技术、优异的高温热解石墨材料和独特的设计,全俄光学物理测量研究所(VNIIOFI)研制出温度高达3 200~3 500K、具有高均匀性和高稳定性的大面积普朗克高温黑体光源。基于低温绝对辐射计的滤光片辐射计迭代测温技术,使高温黑体温度测量不确定度小于0.5K。在德国物理技术研究院(PTB),将这种高温黑体直接用于国际空间站地外太阳光谱测试仪器(SOLSPEC)的辐射定标,定标综合不确定度小于0.5%~1%。2008年德国物理技术研究院(PTB)建成名为计量光源(MLS)的新一代专用同步辐射存储环并投入使用。为调节同步辐射的光谱分布,稳态下其能量可设置为105~630MeV任意值,相应特征波长随之从735nm改变至3.4nm。为在不改变光谱分布情况下改变光强,电子束流可调节11个量级,即从1个存储电子(相当于1pA)到200mA。美国国家标准技术研究院(NIST)在同步辐射紫外辐射装置(SURFⅢ)3号光束线上建立了使用同步辐射的光谱辐照度定标装置(FICUS),为紫外传递标准光源定标,光谱范围200~400nm,相对测量不确定度1.2%(k=2)。新一代同步辐射装置为地外太阳光谱辐照度测量仪器,如SUSIM,SOLSTICE,SBUV,SIM和SOLSPEC等,短波段高精度辐射定标奠定了技术基础。该文描述新型高温黑体和同步辐射装置的建立与发展,光谱辐照度和光谱辐亮度标准的传递及国际比对并评述它们在太阳光谱辐照度测量中的应用。
[Abstract]:In recent twenty or thirty years, the spectral radiation measurement technology has been developed rapidly in the world, driven by the research of solar spectral irradiance measurement and atmospheric quantitative remote sensing. Based on advanced high temperature technology, excellent high temperature pyrolytic graphite materials and unique design, VNIIOFI has developed a large area Planck blackbody light source with high uniformity and stability. The temperature measurement of filter radiometer based on low temperature absolute radiometer makes the uncertainty of high temperature blackbody temperature measurement less than 0.5 K. At the German Institute of Physics and Technology, the high-temperature blackbody was used directly in the radiation calibration of the International Space Station (ISS) Extra-Earth Solar Spectrometer (SOLSPEC). A new generation of special synchrotron radiation storage ring called metrological light source (MLS) was built and put into use by the German Institute of Physics and Technology (PTB) in 2008. In order to adjust the spectral distribution of synchrotron radiation, its energy can be set as 105~630MeV arbitrary value under steady state, and the corresponding characteristic wavelength changes from 735nm to 3.4 nm. In order to change the light intensity without changing the spectral distribution, the electron beam current can be adjusted by 11 orders of magnitude, that is, from 1 stored electron (equivalent to 1 Pa) to 200 Ma. NIST (National Institute of National Standards and Technology) has established a spectral irradiance calibration device for synchrotron radiation on the beam line of synchrotron radiation ultraviolet radiation device (SURF 鈪，
