摘　　要：为了分析不同分光光度计测量光柱镭射纸颜色的精度,选用X-Rite 7000A积分球式、X-Rite MA68Ⅱ多角度、X-Rite Spectro Eye45/0三种不同测量条件的仪器分别对光柱镭射纸的光柱方向和垂直光柱方向进行测量,比较不同仪器测量结果的稳定性和可靠性。数据分析表明,在X-Rite 7000A的大孔径和包含镜面反射光的测量模式下,光柱镭射纸不同位置的光谱均方差较小,沿着光柱方向的色度值变化不大,而垂直于光柱方向的色度值满足线性变化的关系,并且在同一位置测试纸张旋转180°测量所得的色度值基本相同。通过分析垂直于光柱方向不同位置的色度值,提出了一种推算光栅条纹相对刻划方向的方法。In order to analyze the accuracies of the color measurement for pillars pattern of holographic paper with different spectrophotometers, the X-Rite 7000A integrating sphere, X-Rite MA68 Ⅱ multi-angle and X-Rite Spectro Eye45/0 three different instruments with different geometries are selected to measure the positions of along and perpendicular to the pillars. The data analysis indicates that the X-Rite 7000A with the large area view and specular component includes mode shows the smaller spectral mean square error on different positions. The chromaticity values of holographic paper along the pillars measured by X-Rite 7000A are similar while perpendicular to the pillars the chromaticity values fit a good linear relationship. It is found that the chromaticity values are very similar with the same position by rotating 180° and the graving direction of the grating can be deduced by the chromaticity values from different positions perpendicular to the pillars.
