Abstract

Computer-generated holograms are often optimized by error diffusion, projections onto constraint sets (POCS), and direct binary search. We introduce a new method based on interlacing a number of subholograms; each subhologram is optimized by using the POCS to correct the remaining reconstruction error. In addition, once all the subholograms are used, the remaining error is recirculated through all the subholograms until minimum reconstruction error is achieved. A number of experimental results with binary computer-generated holograms indicate that the reconstruction error is reduced to half that which is possible with the POCS method alone.
