Abstract:This paper proposes a method how to make the digital combination color dynamic holograms base on the Fourier transform hologram principle.This method is to get the photos of the object which is in different locations at the same time and in the same locations at different times,and then decompose each image into the RGB three primary colors gray images,simulate holographic coding,recording and reconstruction by the computer software,and compose color images of the three primary colors gray images.Now arranging the reconstruction images of different locations and the different times,the color dynamic holograms can be observed with changes of the space state and the time state.The experimental results show that various dynamic effects can be produced by this method,and the dynamic effects will be changed with the change of alignment rules,angle interval and time interval.
