摘　　要：圆筒状合成彩虹全息图可以将各种二维图象合成为伴有动作的360度立体动态影像,液晶技术的引入应用空间更为广阔,使用多路合成彩虹全息图复制系统解决了这种全息图的批量复制问题.本文对多路合成彩虹全息图接触式复制过程中如何提高复制全息图的成像质量进行了探讨.使用PFG—01胶片拍摄的基元全息图模拟合成彩虹全息图的母板,讨论了分别使用二甲苯及饱和蔗糖水溶液作为匹配液对衍射效率及漫射噪声的影响,并对添加匹配液后产生的再现光角度的偏移进行了分析.Cylindrical multiplex rainbow holographic stereograms can synthesize various 2D images to be a 360° animated 3D image when it is illuminated with a small white light source. It has wider application and exploitation potential when LCD screens are used in this field. We have solved batch manufacturing of this sort of hologram by making use of copying system for multiplex rainbow holographic stereograms. Methods to improve the image quality of contact-copying holograms in the course of replicating multiplex rainbow holographic stereograms are discussed. Using unit holograms that were recorded in Slavich PFG-01 film as simulation of multiplex rainbow holographic motherboard stereograms are analyzed. Influence on the diffraction efficiency and the noise of diffusion when use dimethylbenzene and saturated sucrose solution as matching liquid is discussed. Finally, angular excursion of the reconstructed light beam caused by the above two kinds of matching liquid is discussed in this paper.
