Paper Abstract

For five selected diffraction patterns, the combing effect of phase and spatial quantization to diffraction efficiency is evaluated by checking the effectiveness of the proposed efficiency limit sinc2(1/Z)(eta) slim, where Z is the number of uniformly distributed phase levels and (eta) slim is the efficiency limit due to spatial quantization only. The simulation results show that the effectiveness of the above efficiency limit depends on the number of phase levels, diffraction pattern and the initial random phase. For some patterns, the above efficiency limit approximately holds for both Z equals 4 and Z equals 8.
