The reproduction of computer-generated hologram (CGH) with white light source was realized using a liquid crystal panel instead of holographic film. The Burch-coding CGH was achieved by simulating the interference of a digital image and virtual reference light, displayed on liquid crystal displays and illuminated by a white light-emitting diode. The system is compact and the reconstructed images include full parallax. The full-parallax images of the Fresnel hologram computed with our algorithm were compared with the reproduced images by the rainbow hologram. The results implied this method was ready for the development of real-time three-dimensional color digital holography.
