摘　　要：在众多研究领域中,海洋光学USB2000+是一款被广泛使用的微型光纤光谱仪。然而我们在使用该光谱仪进行测量研究中发现,其在辐射定标、线性度等方面存在系统性的偏差。基于此,我们以行业标准仪器ASD FieldSpec4光谱仪为基准,给出了USB2000+系统性偏差的分析方法,并通过大量对比研究实验,对USB2000+光谱仪关键性能进行定量分析。试验结果表明USB2000+光谱仪在辐射定标准确性、响应线性度、暗电流漂移等方面均存在系统性偏差,并最终导致采集到的数据发生明显偏差。本文针对这些问题,进一步提出了提高海洋光学USB2000+测量精确度的方法,以此提高数据质量。Ocean Optics USB2000+is a widely used miniature optical f iber spectrometer in many research f ields.However,we found that there are systematic deviations in radiation calibration,linearity,etc.in the measurement and research using this spectrometer.Based on this,we used the standard instrument ASD FieldSpec4 spectrometer as a benchmark,gave the analysis method of systematic deviation,and conducted a large number of comparative research experiments to quantitatively analyze the key performance of the USB2000+spectrometer.The results show that the USB2000+spectrometer has systematic deviations in radiation calibration accuracy,response linearity,dark current drift,etc.,and eventually leads to obvious deviations in t he collected data.In r esponse t o t hese problems,t his paper proposes methods t o improve t he measurement accuracy of Ocean Optics USB2000+to improve data quality.
