A color holography that combines computer-generated hologram(CGH)and optical hologram is proposed.Firstly,the colorful image is separated into monochromatic images of red,green and blue automatically by computer.Then,three master holograms(H1)corresponding to red,green and blue information are calculated using computer generated hologram.and the respective diffraction distances between the three monochromatic images and the three computer-generated master holograms are designed accurately by computer.Finally,by combining computer-generated holography with optical holography,a color rainbow hologram(H2)is recorded.By re-illuminating H2 with extended white light,a colorful reconstructed image is acquired.This method utilizes the respective advantage of CGH and optical hologram,and fast-Fourier-transform is introduced to speed up the calculation of CGH,spatial frequency and sampling period of hologram are discussed in ordr to lower the computational complexity.The final colorful reconstructed image resulted from this technology is vivid.
