Abstract

The method of generalized projections is used to design quantized phase holograms that generate gray-scale images. As the number of phase quantization levels decreases, the performance typically degrades. However, performance can be significantly improved by constraining the energy in mutually exclusive cliques of image-plane (far-field) pixels instead of constraining the intensity of each individual pixel. Performance is demonstrated with objective measures (error, efficiency, and variance) as well as with a subjective comparison of images.
