摘要
为了深入研究宽谱段背景光辐射,满足实时测量天空背景辐射的科研试验任务需求,自主设计了一套宽谱段天空背景光辐射计,能实现全天空扫描和定点观测两种测量模式,扩展了可测量波段,完成了200～2500 nm波段积分辐亮度的测量.基于设备的总体结构原理图,详细介绍了各个分系统部件的研制方案,给出了各项详细的技术指标以及设备的标定原理和实验,并对设备的不确定度进行了分析,结果符合不确定度的要求,证明了其可靠性.利用宽谱段背景辐射计在长春地区进行实测,并对数据进行简要分析,测量结果满足辐射变化规律,为科研和具体应用提供了一种新的有效方式.
Abstract
This study aims to enhance the understanding of broadband background light radiation and fulfill the requirements for the real-time measurement of sky background radiation for scientific research and experiments.A broadband sky background light radiometer was developed that is capable of full sky scanning and fixed-point observation,thereby broadening the measurable wavelength range.The radiometer successfully measured integrated radiance across the 200‒2500 nm band.This paper presents the equipment's overall structural schematic and details the development plans for each subsystem component along with comprehensive technical specifications,calibration principles,and experimental procedures.An analysis of the equipment's uncertainty confirmed its reliability by meeting the predefined uncertainty requirements.The radiometer was employed for field measurements in the Changchun area,and the data underwent preliminary analysis.The findings were consistent with the expected radiation variation laws,offering a novel and efficient method for scientific research and practical applications.
