摘要:In binary phase encoding of computer-generated holograms (CGHs), quantization usually decreases the quality of the reconstructed image. For reducing the quantization and coding noises, we developed an adaptive error-diffusion method by using the simultaneous perturbation algorithm in which the diffusion coefficients are adapted for the size and layout of the object. Furthermore, binary phase-encoded CGHs were fabricated by using a mask-transferring process. Its optical reconstructions and numerical reconstructions in a Fourier setup were demonstrated.
