摘　　要：设计了一种分光测色仪,使用氙灯作为分光测色仪的测量光源,设计机械结构调整紫外部分的能量在整个氙灯发光强度中的比例。使用荧光物质比例确定的标准色板作为标准物质对仪器和标准仪器进行校准。设计算法对照明光源进行修正,使得照明光源的紫外光谱辐射强度和标准仪器一致,进而降低台间差。此外,设计了实验对方案效果进行验证。未应用所提方案的仪器在CIELAB均匀颜色空间中:测量无荧光材料颜色台间差ΔE_(ab)的最大值为0.88,平均值为0.44;测量有荧光色台间差ΔE_(ab)的最大值为13.69,平均值为3.46。应用所提方案后仪器在CIELAB均匀颜色空间中:测量无荧光色台间差ΔE_(ab)的最大值为0.88,平均值为0.38;测量有荧光色台间差ΔE_(ab)的最大值为3.88,平均值为1.04。实验结果证明,使用所提方案可以较好地提升不同仪器之间对荧光色测量的台间差水平。In this paper,a spectrophotometer is designed.The xenon lamp is used as the measuring light source of the spectrophotometer,and a mechanical structure is designed to adjust the proportion of ultraviolet energy in the luminous intensity of xenon lamp.The standard color plate determined by the proportion of fluorescent substances is used as the standard substance to calibrate the instrument and the standard instrument.The algorithm is designed to modify the instrument light source to make the ultraviolet spectral radiation intensity of the illumination light source is consistent with that of the standard instrument,so as to reduce inter-instrument agreement.In addition,experiments are designed to verify the effect of the scheme.The maximum value and average value of inter-instrument agreementΔE_(ab)of nonfluorescent materials measured by instruments without the proposed scheme are 0.88 and 0.44 in CIELAB uniform color space,and that in the situation with fluorescence color are 13.69 and 3.46.After applying the proposed scheme,the maximum value and average value of inter-instrument agreementΔE_(ab)of non-fluorescent materials measured by instruments are 0.88 and 0.38 in CIELAB uniform color space,and that in the situation with fluorescence color are 3.88 and 1.04.The experimental results show that the proposed scheme can improve the inter-instrument agreement level of fluorescent color measurement between different instruments.
