高精度紫外标准辐射计

High-Accuracy Ultraviolet Standard Radiometer

以美国国家标准研究院(NIST)标准探测器为核心,加入分光系统,数据采集系统,共同构建一套具有自身响应度标准的高精度紫外标准辐射计。并对其内部核心元件进行了性能测试,在NIST标准探测器响应度已知的情况下,经过理论推导并加入相应的修正因子,最终得到高精度紫外标准辐射计的响应度标准。并对高精度紫外标准辐射计进行了精度(达1.3%)分析,证明了该辐射计具有良好稳定性,较高精度及自身响应度标准。

After adding the beam-splitting and data-acquisition system,a set of high-accuracy ultraviolet standard radiometer（HAUSR） with self responsibility standard is constructed by using the standard detector of National Institute of Standards and Technology（NIST） as core element.The core elements of HAUSR have been tested.With the responsibility of the standard detector known,the responsibility standard of HAUSR had been deduced by theoretical derivation and adding corresponding correction factor.The accuracy（to 1.3%） of HAUSR is analyzed.It proves the HAUSR system has fine stability,high accuracy and self responsibility standard.
