Abstract

It is well known that the iterative stepwise quantization algorithm is very powerful for the optimization of amplitude digital Fourier transform holograms. We suggest a pre- iterative process to uniform the histogram distribution of the Fourier transform of the input image in order to reduce the reconstruction error of amplitude digital Fourier transform holograms. Simulation results show that the reconstruction error can be reduced much when our pre- iterative process is used in the iterative stepwise quantization algorithm.
