为满足高精度太阳光谱辐照度绝对测量的需求,研制了太阳光谱辐照度绝对测量系统及其定标单色仪。介绍了太阳光谱辐照度绝对测量的现状,并着重介绍了太阳定标单色仪和积分球太阳光谱仪的设计方案,以及高精度辐射定标传递链路。设计用于太阳光谱辐照度绝对测量的太阳定标单色仪和积分球太阳光谱仪,通过低温绝对辐射计和太阳定标单色仪实现绝对定标,使积分球太阳光谱仪测量数据可溯源至国际基本单位(SI)。结果表明:太阳定标单色仪的光谱范围覆盖300~2 400 nm,光谱分辨率为3~10 nm,输出单色太阳光功率的不确定度为0.2%~0.5%;积分球太阳光谱仪的光谱范围覆盖300~2 500 nm,光谱分辨率为1~8 nm,太阳光谱辐照度绝对测量精度最高可达0.5%。用低温绝对辐射计和太阳定标单色仪绝对定标积分球太阳光谱仪,可以实现高精度太阳光谱辐照度的绝对测量。
In order to meet the demand of high precision of absolute solar spectral irradiance(ASSI) measurement
ASSI measurement and its calibration monochromator were researched. The present situation of ASSI measurement was introduced
and the project of the solar calibration monochromator (SCM) and the solar spectrometer with integrating sphere (SSIS) was emphatically recommended. The SCM and SSIM for ASSI measurement were designed. The absolute calibration of SCM was performed by the space cryogenic absolute radiometer (SCAR)
and the measurement data of SSIS was made traceable to the international system of units (SI). The spectral range of SCM covers 300-2 400 nm
the spectral resolution is 3-10 nm
and the uncertainty of solar homochromy power is 0.2%-0.5%. The spectral range of SSIS covers 300-2 500 nm
the spectral resolution is 1-8 nm
and the highest accuracy of ASSI measurement is 0.5%. The results show that the SSIS calibrated by SCAR and SCM can achieve high precision ASSI measurement data.
