One method of realizing color holographic imaging using one thin diffractive optical element (DOE) is proposed. This
method can reconstruct a two-dimensional color image with one phase plate at user defined distance from DOE. For
improving the resolution ratio of reproduced color images, the DOE is optimized by combining Gerchberg-Saxton
algorithm and compensation algorithm. To accelerate the computational process, the Graphic Processing Unit (GPU) is used.
In the end, the simulation result was analyzed to verify the validity of this method.
