摘　　要：基于色度学原理和全息图的基本物像关系,提出利用等效编码法制作彩色彩虹全息图。首先,将空间坐标确定的彩色物点,编码为三个不同空间坐标的三基色等效物点,它们的空间坐标由全息物像关系确定。在一全息记录面上的不同位置,计算出三基色物点对应的三条线全息图。然后,利用平面共轭光再现三线全息图,在原彩色物点位置能看到完全重合的三分色全息图再现像,重合像与参考光干涉后,获得彩色全息图。经实验验证,此方法有效解决了两步法制彩色全息图时,三分色全息处于同一平面再现时,它们的再现像无法重合的问题。Based on the colorimetric principle and the relation between the object and hologram image, a method of making color hologram by equivalent coding method is proposed. Firstly, coding the color object into three primary colors which have different coordinates. The coordinates are decided by the relationship between the object and hologram image. Three threadiness holograms are calculated in the different place of a plane. Secondly, reappearing three threadiness holograms by the conjugate light, three images will overlap in the place where have the color object, the images interfered by reference light to be a color hologram. The result shows that this method can solve the problem when three threadiness holograms place in the same plane, their images can＇ t overlay.
