Study upon Metal Dies Copying Technology of the Relief Rainbow Hologram;

After its holograms are modified (taken off strong adsorbing humidity groups in gelatin), the holograms of high diffraction efficiency, which is stable in high humidity environment for long time, were obtained.

In this paper,the influence of devcloper composition on diffraction efficiency of holograms is investigated.

The article analyzes and explores factors that influence the imaging,summarizes some specific methods of making holography successful and improving the quality of holograms,such as stabilizing the system of filming,adjusting light path as well as reappearance of observation.
