Abstract

We address the problem of designing pure 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. Although the method of generalized projections is known to occasionally converge to erroneous solutions, such solutions were not observed in this analysis. Several reconstructed light intensities are furnished and the quality of the reconstruction is discussed.
