摘　　要：为了获取高质量的彩色动态全息,采用计算机编码的方法,提出了一种制彩色动态全息的新方法。根据色度学和采样原理,将任一分动作物点分解为红、绿、蓝三基色物点,计算编码调整三基色物点的位置,使它们对应的含体视对的3张分色全息图放置在同一平面上,经共轭光再现后,所有体视对的再现像能在空间上完全重合,并记录重合像与参考光干涉后的彩色全息图。结果表明,彩色全息图经再现后,随着人眼位置的移动,可见不同的动作像,从而实现彩色动态效果。此方法能有效解决彩色动态全息图再现像难重合、对实验条件要求高的问题;且操作简单易行,能有效避免一些不必要的噪声,在3维显示方面具有较好的应用价值。In order to make a nice hologram,a new method to create a color dynamic hologram by computer coding was proposed.According to the colorimetry principles and the sampling principle,an object point of every behaves can be resolved into three primary color objects as red,blue and green,whose coordinate data are coded by the computer in order to let their monochromatic stereoscopic holograms have a pefect overlap when they are placed in a plane and reappeared by conjugate light.The overlapping images interferenced with the reference light to form a dynamic color hologram.The experiment shows that a dynamin visual can be seen with the movement of the position of the eyes when the color hologram is reproduced.This method can effectively solve the problem that difficult overlap of images with low experimental conditions,which also avoid some unnecessary noise with simple operation,and has good application value in 3-D display.
