Paper Abstract

Using a two-dimensional fast Fourier transform is an efficient way to calculate a kinoform. High-speed processing of large amounts of data points (e.g., a 512×512 matrix) can be accomplished using a kinoform. Real-time computer-generated hologram calculation has been widely pursued. To this end, use of the graphics processing unit (GPU) or multiprocessing methods are becoming popular for high-speed processing. We used the GPU method coupled with multiprocessing to construct a kinoform and measured the efficiency of this method.
