摘　　要：为了研究内窥镜系统整体色还原性以及各个部份对色还原性的相互影响,本文用不同类型和质量的光源,采用分段测试法对内窥镜透过率进行测试分析;测试不同系统搭配下的显色指数,对系统色还原性进行分析。试验证明光源类型不会影响内窥镜透过率的测试结果,而光源质量对内窥镜透过率测试结果影响较大;光源类型的选择与系统色还原性不具规律性。因此,需要单独考量光学内窥镜系统色还原性。In order to study the overall Color Rendering Index (CRI) of optical endoscope systems andthe impact of each component on the CRI, the transmission rate of the endoscope was tested by piecewisemethod using different types of light sources with different quality. The CRI under different systemconfiguration was tested. The CRI of the system was analyzed. The experiment showed that the typeof light sources had minimal impact on the transmission rate of the endoscope. By contrast, the qualityof the light sources has stronger impact on the test result of transmission rate. The selection of the typeof light sources has no significant relevance with the CRI of the system. Thus, it needs to be evaluatedindependently.
