The significance of the initial distribution for three iterative calculation techniques of diffractive elements; simulated annealing, direct binary search, and Fourier transform algorithm, is investigated. Depending on the initial distributions, convergence problems may occur. Techniques to calculate special initial distributions for the three methods are described: these significantly improve the capabilities of the iterative techniques.
Peter et al. (1993) studied this question.
