title = "Generation of enhanced optimal sampled phase-only hologram",
abstract = "Optimal sampling method is effective in generating phase-only hologram. In this approach, the intensity of a source image is multiplied with an optimal sampling lattice, and converted into a hologram. Subsequently, the phase component of the hologram is retained as a phase-only hologram. The optimal sampling lattice is optimized through direct binary search so that the reconstructed image is closest to a given training image. A hologram generated with this method is known as an optimal sampled phase-only hologram (OSPOH). The reconstructed image of an OSPOH is generally good, but its quality cannot be further improved by extending the optimization process. In this paper, an enhancement on the reconstructed image of OSPOH through time-division filtering is presented. Experiment results revealed that the proposed method can lead to significant enhancement on the reconstructed image.",
