The diffraction efficiency η of analog and quantized amplitude holograms is treated. Possible ways to manipulate η are discussed in terms of utilization of different kinds of freedom in the reconstructed field. Iterative methods to increase η are suggested, and experimental results are presented. The methods are based on iterative Fouriertransform algorithms. Results of iterative and noniterative quantization techniques are compared with respect to their dependence on the original analog hologram.
