A technique called computer-generated dynamic rainbow hologram,which combines computer generated hologram and synthetic technique for double-view dynamic rainbow hologram is presented.According to the characteristic of that rainbow hologram's elementary hologram is “line-element hologram”and the binocular stereo vision,it computes two slices from the “line-element hologram. And right and left eye views are made respectively corresponding to the two slices. The rainbow hologram's slot image was divided simultaneously. The aim of dynamic display can be realized if the region of the slot image corresponds to the object's different gesture. The new method was applied,and the elementary experiment result is given.
