The computation of binary Fourier transform holograms can be viewed as three sequential steps: 1) quantization of the object spectrum, 2) sampling of the object spectrum, and 3) binarization of the quantized, sampled spectrum to form the plottable hologram. The errors from each step in the computation are cumulative, and depend on the particular hologram encoding method used, as well as the parameter values associated with the process. A number of different methods for hologram synthesis are compared experimentally in terms of these errors. The results are related to an earlier analysis of images reconstructed from digital holograms. A procedure for optimally quantizing the object spectrum is also described.
