    彩色亮度计光源色度的不确定度分析

    2008-02-25

     

    摘  要:JJG 211—2005亮度计检定规程已颁布实施,它同时囊括了亮度计和彩色亮度计的检定,增加了光源色度参数的校准。在实施实践中,校准彩色亮度计所用的标准反射色板采用了色差计校准用的一套标准反射色板,校准时的标准值取标准反射色板溯源证书中的A/2,0/45的数据。从彩色亮度计中光源色度参数的实验数据,以及对其测量结果的不确定度分析,均证明新规程校准方法正确,而共用标准反射色板亦可行,校准效果良好。

    Abstract: National verification regulation for luminance meter, JJG 211-2005 was published and implemented. This regulation was used to verify either luminance meter or color one, and calibration of illuminant chromaticity was required. During color luminance meter calibrating, its standard reflection shade guide was the same as that for colorimeter calibration, and these standard values A/2,0/45 according to certificate of standard reflection shade guide were used. It is proved that method of this new verification regulation is correct, standard reflection shade guide for colorimeter calibration could be used in color luminance meter calibration, and its calibration results is very well according to experimental data of illuminant chromaticity parameters for color luminance meter and measurement uncertainty.

     

    Key words: Color luminance meter; Illuminant chromaticity; Calibration; Standard reflection shade guide; Verification regulation; Colorimeter; Uncertainty
