通过调整R,G,B三色激光入射DMD的角度来解决彩色全息光电再现时各颜色分量的再现像中心无法重合这个问题.以彩色图的一单色分量为基准,对原始图中的物体进行倍率色差的消除;通过调整三色分量在全息图中的位置以及调节三色激光器入射角度来消除横向位置色差;设计一套基于单片DMD的无透镜式彩色全息投影系统,并通过光电再现实验,得到彩色全息再现图像.所提出的方法不仅再现光路简洁,而且不需要引入时序控制装置,仅需单片DMD就可以直接再现出彩色物体.

The problem that the reconstructed image center of each color component can not coincide during the optoelec-tronic reconstruction of color holography is solved by adjusting the incident angle of the R,G,B color lasers. Firstly,the magni-fication chromatic aberration of the original image is eliminated by taking a single color component of a color image as the reference. Secondly,the transverse location chromatic aberration is eliminated by adjusting the incident angle of these lasers. Finally,a lensless color holographic projection system based on DMD was designed. Based on the experiment of optoelectronic reconstruc-tion,color holographic reconstruction images were obtained. With this method,not only the optical path of reconstruction is more intuitive,but also the timing control device is needless,and the color objects can be reproduced just by single DMD.
