岩心光谱扫描仪是近年来发展起来、用于岩心光谱和图片在线检测的仪器，它可以对岩心进行数字化，从而实现岩心自动编录，为地质科研、矿床研究和外围找矿提供依据，同时通过岩心数字化，可以建立岩心网上数据库，解决岩心保存带来的成本问题，实现资源共享。岩心光谱测量数据的质量直接影响矿物识别、参数反演结果的可靠度，因此进行岩心光谱测试服务之前针对拟采用仪器进行数据质量评估是一项非常重要的工作。结合自主研发的CSD350A型岩心光谱扫描仪，以光谱学基本理论、光谱分析方法、岩心光谱分析要求等为基础，深入探讨了岩心光谱数据质量评估方法、评价准则、目标参数等关键问题，对自主研发的岩心光谱扫描仪数据质量进行了全面评估，表明仪器光谱测试功能的可靠性和有效性。实验测试表明，本方法所涉及的检测项目和检测参数，能够很好地反映岩心光谱扫描仪所测光谱的反射率光谱、波长精度、重复性及信噪比指标，从而对岩心光谱扫描仪数据质量做出正确评价，为商业服务提供数据质量依据。在目前缺少相关评估标准的情况下，本研究提出的评估方法对于岩心光谱测试工作的开展具有较大的应用价值。

Core scan is the instrument used for core spectrum and pictures detection that has been developed in recent years . Cores’ data can be digitized with this equipment ,then automatic core catalog can be achieved ,which provides basis for geological research ,mineral deposit study and peripheral deposit prospecting .Meanwhile ,an online database of cores can be established by the means of core digitalization to solve the cost problem caused by core preservation and share resources .Quality of core data measurement directly affects the mineral identification ,reliability of parameter inversion results .Therefore it’s very important to quasi‐manage the assessment of data quality with the instrument before cores’ spectrum testing services .Combined with the independent R&D of CSD350A type core scan ,and on the basis of spectroscopy basic theory ,spectrum analysis methods ,core spectrum analysis requirements ,key issues such as data quality assessment methods ,evaluation criteria and target parameters has been discussed in depth ,and comprehensive assessment of independent R&D of core scan has been conducted ,which indi‐cates the reliability and validity of spectrum measurements of the instrument .Experimental tests show that the methods inclu‐ding test parameters and items can perfectly response the measurements of reflectance spectrum ,wavelength accuracy ,repeat‐ability and signal to noise ratio with the instrument .Thus the quality of core scan data can be evaluated correctly ,and the foun‐dation of data quality for commercial services can be provided .In the case of the current lack of relevant assessment criteria ,the method this study proposes for the assessment has great value in the work of core spectrum measurements .
