Special-purpose diffractive optical devices are often designed by iterative methods without consideration of convergence properties and related factors that affect performance. We examine the properties of iterative algorithms in a vector-space setting and illustrate, with examples, differences in convergence performance based on starting point, sequential versus parallel projections, and intersecting versus nonintersecting sets.
