Abstract

Weighted iterative algorithm is presented for generating phase holograms with high-quality reconstruction. The reconstruction plane is partitioned into two parts where different constraint strategies are addressed during the iteration process. Signal region of the reconstruction plane is constrained directly according to the amplitude distribution of the target pattern, whereas non-signal region is constrained indirectly by total energy control of the hologram plane based on the energy conservation principle. The weighted iterative algorithm can improve the reconstruction quality by broadening the optimizing space of the calculated phase distribution.
