Abstract
The numerical iterative method of design of multi-plane Fresnel holograms is presented. It assumes encoding several flat grayscale images into a single thin phase-only element. Each image is placed at a variable distance and the number of images is not limited, thus many interesting applications can be considered. The paper presents the application of such holograms to reconstruct a colorful two-dimensional image with the use of a single spatial light modulator and three laser beams, i.e. red, green and blue. The given solution helps reduce the total cost of a potential holographic projection device since a single light modulator is used instead of three and no refractive volume optics is necessary to form the final image. The reconstructed three component RGB images overlap to form the color image on the screen. Sub-images are reconstructed simultaneously therefore no time-domain sequential switching is required, which is known to cause the obstructing rainbow effect. The proposed holographic projection method allows to obtain a fine image even when several pixels of the light modulator are damaged. The description of the method is given, followed by the results of numerical simulations.
