提出计算机制三维物体彩色全息图的新方法·通过理论分析表明,在满足一定的条件下,三个不同原色的点光源所产生的全息图光栅结构和距全息图不同距离的三个同色物点的光产生的全息图光栅结构是等价的·根据这一原理并参照彩虹全息技术,研究了物体三原色信息光分布的编码方法和全息图的算法,用单波长计算实现彩色全息图的制作,同时,较为完满地解决了全息图叠加和色串扰问题·实验结果证明了该方法的可行性及有效性·

A novel method for making color rainbow hologram of 3D object has been proposed. Theoretical analysis has indicated that the grating struction of holograms shot by three color object points in same situation is equivalence to those shot by three monochrome object points in different proper situation when satisfying some given conditions. Combining the technique of rainbow hologram,it has studied the coding way of the information distribution for trilolor light on the hologram plane, the hologram algorithm and color hologram facture with monochromatic light,at the same time,it has worked out a satisfying solution to the problem of hologram superposition and color crosstalk. The feasibility and efficiency of the method are confirmed by experimental results.
