Multiplex rainbow holographic stereograms can record objects with 2D image, 360° cylindrical holographic stereograms can show animated 3D image when it is illuminated with a small white light source.

Research on copying multiplex holograms;

From visibility of interference fringes,the quality of sensitive material,exposure and de-velop,this paper analyses the main factors which affect rainbow holograms diffraction effi-ciency,and puts forward sonle methods to inlprove diffraction efficiency in practical work.

Fabrication technique and special characteristic of rainbow holograms with large illumination angle;

Design and realization of photographing the color-coding rainbow hologram;

This paper discusses the technology and method of making one-step rainbow hologram, and points out some points for attention and main factors that affect the quality of hologram.
