摘要: 为高精度监测太阳光谱辐照度变化, 设计一款高精度太阳光谱辐照度仪用于获得太阳光谱辐照度数据。 该辐照度仪设计了三种光路完成性能指标, 其主光路用于测量光谱辐照度, 参考光路用于波长标定, 太阳跟踪 光路用于室外精密跟踪太阳。详细介绍了辐照度仪主光路的设计, 主光路采用 Fe´ry 棱镜进行色散与会聚, 辐照 度仪入射狭缝通过 Fe´ry 棱镜成像到棱镜焦平面。通过旋转棱镜, 在辐照度仪焦平面通过两个单元探测器获得 380∼2500 nm 光谱辐照度。通过理论分析和实验验证, 在 380∼2500 nm 光谱范围内仪器的光谱分辨率小于 40 nm。采用标准灯对太阳光谱辐照度仪进行光谱响应范围验证, 结果表明仪器的光谱范围满足测量需求。

Abstract: In order to monitor the change of solar spectral irradiance with high accuracy, a high accuracy solar spectral irradiance monitor is designed to obtain solar spectral irradiance data. The instrument has three independent optical paths. The main light path is used to measure solar spectral irradiance, the reference light path is used for spectral calibration, and the solar tracking light path is used for precision solar tracking outdoors. The design of the main light path is introduced in detail. Fe´ry prism is used for dispersion and convergence in the main light path, and the entrance slit of the monitor is imaged to the focal plane of the Fe´ry prism. Two photodiodes are used to detect the spectral irradiance from 380 nm to 2500 nm by rotating the prism. Through theoretical analysis and experimental verification, it is shown that the full width at half maximum of the monitor is less than 40 nm in the 380∼2500 nm spectral range. Standard lamps are used to verify the spectral response range of the solar spectral irradiance monitor, and the experimental results show that the spectral range of the monitor meets the measurement requirements.
