为快速获取天空背景辐亮度，提出了一种基于DTL-1型天空辐亮度仪的宽谱段测量方案。分析了天空可见到近红外波段（400~1000 nm）积分辐亮度的测量原理，确定了宽光谱测量的响应系数和光视效率，并对测量结果进行了误差分析。利用光谱仪对仪器进行了线性度检验与测量数据对比，结果表明两者相对误差在10%之内，验证了仪器测量的可靠性，数据精度可以满足工程应用的要求。利用DTL-1型天空亮度仪分别在我国西南地区和合肥地区开展了全天空辐亮度的扫描测量，并对两地的实测数据进行了简要分析。

A measurement program of wide-wave band based DTL-1 sky brightness meter is developed to gain the real time sky background radiance fast. The principle for measuring the integral radiance in wave range from visible to near-infrared (400~1000 nm) is analyzed. Furthermore, the response coefficient and luminous efficiency are calculated, and an error analysis for the measurement results is made. The linearity checking of the DTL-1 and the data are carried out using spectrometer. The relative error is below 10%, which indicates the credibility of the instrument. The precision of the instrument can satisfy the requirement on real application. The all sky radiances in Hefei and Southwest districts are measured by using DTL-1, and the measurement data in the two districts are analyzed in brief.
