组合数字彩色动感全息图的研究

提出了一种基于傅里叶变换全息原理制作数字彩色动感全息图的方法。该方法通过获取待记录对象同一时刻不同位置状态和同一位置不同时间状态的多幅图像,将每幅图像分解为RGB三基色灰度图,利用计算机软件编程进行全息编码、记录与模拟再现,再将三基色灰度图合成为彩色图像。将不同位置和不同时刻的再现像按预定方式排列,当人眼移动时由于视觉暂留效应,会看到随着空间状态变化和时间状态变化的彩色动感全息图。实验结果表明,通过该方法制作的全息图能够产生丰富的动感效果,且随着排列规则、角度间隔、时间间隔的变化,动感效果也发生相应变化。

Study on the digital combination of color dynamic hologram

This paper proposes a method how to make the digital combination color dynamic holograms base on the Fourier transform hologram principle.This method is to get the photos of the object which is in different locations at the same time and in the same locations at different times,and then decompose each image into the RGB three primary colors gray images,simulate holographic coding,recording and reconstruction by the computer software,and compose color images of the three primary colors gray images.Now arranging the reconstruction images of different locations and the different times,the color dynamic holograms can be observed with changes of the space state and the time state.The experimental results show that various dynamic effects can be produced by this method,and the dynamic effects will be changed with the change of alignment rules,angle interval and time interval.
