摘　　要：本文提出了一种合成狭缝彩虹全息术，合成狭缝的位置可以在三维方向随意移动。Rainbow holography with synthetic slit is presnted in this paper. The position of synthetic slit can be translated in three-dimensional directions. Diffuse three-dimensional object and imaging lens are translated uniformly on (X,Y) plane in the same direction and synchronous way. The propagation direction of coherent plane wave illuminating the object is situated on (X,Z) plane. As a result of this process, a sine function modulating the complex amplitude distribution of the object is presented on somewhere from the holographic plate. The synthetic slit is formed. The centrat positiom of the synthetic slit depends on the translation direction of the object and imaging Lens,spatal frequency of illuminating wave in Xodirection, relatine distance of refrnence source and reconstruction source from the holographic plate.
