Color hologram reconstruction based on single DMD

Because of the magnification chromatic aberration and the transverse chromatic aberration caused from different wavelengths of color lasers in the process of color holographic optoelectronic reconstruction based on DMD, the reconstructed holograms of three color components can not coincide. Firstly, on the reference of blue color component, the magnification chromatic aberration of the original image is eliminated. Secondly, according to the analysis of the incident angles of three lasers, the transverse chromatic aberration is eliminated by adjusting the incident angles. At last, the synthesized color hologram is obtained by means of the experiments based on DMD. The method proposed in this paper does not use any lens, so there is no axial chromatic aberration.
