A method to reduce the size of LUT for generation of a full-color CGH using a relation between distance and wavelength in Fresnel diffraction

Even though many kinds of approaches to generate CGH patterns of the 3D object image were suggested, but most of them could be applied to single-color 3D objects, so that we still need some possible approach for implementation of full-color holograms for the 3D images. In this paper, a method to reduce the size of required N-LUTs for generating of a full-color CGH patterns using a relation of distance and wavelength in Fresnel diffraction is proposed. In addition, some simulations with test images are carried out, and finally the feasibility of the proposed method was confirmed.
