摘　　要：基于色度学原理,任一彩色物体可分解为红、绿、蓝三基色物体。因此制作彩色彩虹全息图时,可将原彩色物体分解成三个等效基色物体,然后根据全息图的物像关系计算出三个基色物体的等效位置,再由查表法计算出三个等效基色物体在彩虹全息记录面上的总物光分布,与参考光干涉后获得线全息图。线全息图经空间光调制器输出之后,白光再现下可见彩色物体像。该方法的优点在于:用一副等效彩虹全息图替代了传统彩色全息图中的三副基色全息图,并且计算机制等效彩虹全息图,方便设置参数,减少了全息图噪声,提高了全息图质量。Based on the colorimetric principle,a color object can be coded into a red object,a green object and a blue object. So,the color object can be coded into three primary color objects in making color rainbow hologram. The coordinates of three primary color objects can be calculated according to the relationship between the objects and their holograms,then the diffraction wave from three primary color objects in the hologram plane can be calculated,which is interfered through a reference light to form a hologram. After the hologram is shown by SLM and is illuminated by the light with continuous spectrum,three primary color images will superposite in space to form a color image. This method use a equivalent hologram instead of three monochrome holograms,which provide a simple and convenient way to make a high-quality color hologram.
