Abstract
The search spaces in nonlinear optimization phase retrieval problems are of high dimensionality, making them difficult to visualize. Using a simplified low-order model, we explore the shape of the phase retrieval error surfaces using two-dimensional (2D) slices to visualize the relationship between different aberrations. We show how different pairs of aberrations exhibit very different coupling with one another and different distributions and frequencies of local minima, and discuss how this relates to the phase retrieval capture-range problem.
