A new method for manufacturing the true color holograms is put forward based on computer generated holography. The basic principle is given and the new true color hologram is realized with the proposed method. The experimental results and the correlative problem are discussed in details. The real color holographic technology is realized with Matlab. The following results are obtained through experiment: 1) Replacement problem of realized hologram can be solved with the basic principle of invariability of Fourier transform. 2) Quality of realized hologram can be improved with filter wave method. 3) Intensity of realized hologram can be enhanced effectively. 4) The method of realized hologram is simple and economic to improve its property.
