The iterative alternating projections onto constraint sets (POCS) algorithm is applied to the design of computer-generated holograms (CGH's). The performance of the resulting CGH's is compared to those designed by the non-iterative error diffusion algorithm and direct binary search (DBS), which is another iterative technique. Both iterative methods are distinguished from earlier iterative methods for CGH design by their ability to simultaneously control the amplitude and phase of the reconstructed wavefront.
