Paper Abstract

Several approaches for increasing the speed and simplicity in computation of the digital holograms of the 3-D object have been presented with applications to real-time display of holographic images. So far, a look-up table (LUT) approach in which the pre-calculated elemental interference patterns for all possible points of the object are provided, has gained a lot of speed increase. But the greatest drawback of this method is the enormous size of the LUT. In this paper, a novel LUT method to dramatically reduce the number of pre-calculated elemental interference patterns required for computation of digital holograms compared with that of the conventional approach is proposed. Some experimental results finally reveal that the computation speed and the required memory size of the proposed LUT approach are found to be 48.8 times faster than that of the ray-tracing method and 217 times smaller than that of the conventional LUT method, respectively.
