摘　　要：为提高计算机制彩色全息颜色再现的质量,对彩色全息的颜色传递、变换以及产生的色差问题进行了较为深入的研究.鉴于计算彩色全息所用的目标物体彩色信息都来自标准制式的摄像系统,与彩色全息必须采用的光谱色三原色不一致,为了尽可能地减少再现色差,选取与标准制式相匹配的显示器三原色的主波长作为计算彩色全息的三原色,在此基础上分析了计算彩色全息图RGB颜色系统与CIE1931-XYZ系统之间的三原色转换关系,并对全息再现像的颜色误差进行了计算和讨论.In order to improve the quality of reconstructed images of computer generated color hologram, color transmission, color transformation and chromatic aberration of computer generated color hologram were studied. Because the color information of three-dimensional object was acquired from the standard camera system, the main wavelengths of three primary colors of the display which matched the standard mode were chosen as three primary colors of computer generated color hologram to reduce color aberration of reconstructed images. Based on this way, the conversion between color hologram RGB system and CIE1931-XYZ system was analyzed. The color aberration of reconstructed images was discussed and the result was presented.
