Abstract
In order to improve the reconstruction quality of hologram, the iterative layer-oriented angular spectrum optimization (ILASO) algorithm is proposed in this paper, which combines non-iterative and iterative methods to achieve full color holographic three-dimensional (3D) display. In this paper, the hologram is generated by layer-oriented angular spectrum diffraction, and then the hologram is optimized by error feedback iteration, so as to reduce the speckle noise and improve the reconstruction quality of the hologram. Simulation results show that the holographic reconstructed image has strong detail representation ability, weak speckle noise and small crosstalk, which is suitable for complex 3D scenes and has excellent holographic 3D display ability.
