摘要
本研究采用手持积分球式分光光度计X-Rite Ci64及台式积分球式分光光度计Ci7800对7种镭射纸张进行多次颜色测量,寻找最合适的孔径值。结果表明,在Ci78003.5 mm和X-Rite Ci646 mm的孔径下,获取的纸张颜色更准确。多次测量后谱差约0.6,最小谱差仅0.15,光谱拟合度均可达99%,平均色差0.5左右。在后续的光柱镭射纸颜色测量过程中,选择较小孔径的仪器进行颜色测量,所获取的颜色更准确。
In this study,a handheld integrating sphere spectrophotometer(X-Rite Ci64)and a benchtop integrating sphere spectrophotometer(Ci7800)were used to perform multiple color measurements on seven kinds of holographic paper.The results indicated that more accurate paper colors were obtained with the Ci78003.5 mm and X-Rite Ci646 mm apertures.The spectral difference after multiple measurements was about 0.6,and the minimum spectral difference was only 0.15.And the spectrum fitting coefficient could reach 99%.The average color difference was about 0.5.During the subsequent color measurement of the light pillars pattern of holographic paper,whose color obtained was more accurate by choosing an instrument with a smaller aperture for color instrument.
