Wide-viewing-angle color display is an important goal of holographic display. A method to achieve wide-viewing-angle color holographic display using white light illumination and a rotating mirror is proposed. By using spatial multiplexing method, each color component hologram is loaded on one third area of the spatial light modulator (SLM). White light LED illuminates the SLM after a filter, and complete over lapping of reconstructed image can be realized by adjusting the original size of three color components. When holograms are loaded on SLM with different viewing angles, reconstructed image is reflected in different locations by rotating mirror. The switching speed of the holograms should be the same with rotation speed of mirror. When the switching speed is fast enough, the wide-viewing-angle holographic reconstruction can be seen according to the persistence of vision effect. The experimental result verifies the feasibility of the proposed theory.
