Abstract

We address the problem of designing phase gratings that generate prescribed light intensities in the far field. The method of generalized projections is used to find a solution consistent with prior constraints and available data. While the method of generalized projections is known to converge to erroneous solutions occasionally, such solutions were not observed in this problem.
