黄色翡翠的颜色测量及分析

根据色度学原理,利用美国Ocean Optics公司的USB2000＋光纤光谱仪对黄色翡翠进行测量与分析,量化黄色翡翠颜色的参数指标,包括其CIE 1931色度坐标、主波长、彩度、明度和CIE1931色品图等。依据主波长及色调角,可区分黄色翡翠颜色的主色调。实验结果表明,利用光纤光谱仪、适当的照明方式及光谱采集方法,应用色度学原理,可以客观、定量地描述黄色翡翠的颜色,可作为评价黄色翡翠颜色的适用技术。

Color Measurement and Analysis of Yellow Jadeite

Based on the colorimetry principle,yellow jadeite has been measured and analized by USB2000＋fiber optic pspectrometer of American Ocean Optics.The color parameter index of the yellow jadeite including its CIE1931 chromaticity coordinates,dominant wavelength,chroma,lightness and CIE1931 chromaticity diagram have been quantized.The dominant hue of the yellow jadeite can be distinguished by its dominant wavelength and hue angle.The experiment result proves that the color of the jadeite can be objectively and quantitatively described by using fiber optic pspectrometer,adequate illumination and appropriate spectrum sampling method along with the colorimetry principle.This method will be an appropriate technique for yellow jadeite color evaluation.
