摘要
基于色度学原理,研究了彩色计算全息颜色的匹配问题,给出了电子显示色系下颜色量与计算全息物光波振幅之间的等色传递关系.首先,讨论了电子显示色系和彩色计算全息色系之间的颜色传递问题,并且给出了这两个色系下颜色量的转换方法.其次,以彩色全息再现像与原始计算目标颜色一致为目的,分析了彩色计算全息色系下的颜色量和与其对应物光波振幅的关系,并得出了颜色量和物光波振幅间应满足的一般方程.最后,本文选取PAL制式彩色显示色系下的彩色目标为全息图计算物体进行了彩色全息显示实验,结果表明本文所述彩色计算全息颜色匹配方法是有效的.本文的研究工作将为彩色计算全息显示的实用化奠定一定的理论基础和技术依据.
Color matching issue of （Color Computer-generated Holography, CCGH） is researched based on colorimetric principle. The conversion between color quantity in electronic display colorimetric system and amplitude of object light in CCGH colorimetric system is given. Firstly, the conversion between color quantities in electronic display and CCGH colorimetric system is discussed. Then, the conversion method for color quantity in the two colorimetric systems is given. Secondly, isochromatic transfer relationship of color quantity and amplitude of object light field is proposed. Thirdly, we chose a color image from PAl. RGB colorimetric system as an experimental object of CCGH. The experimental results demonstrate that our novel approach is feasible. The research of this paper will provide theoretical and technical basis for practical use of CCGH.
