Abstract
Space-invariant, multilevel, diffractive phase elements are designed f or large-scale pattern-formation tasks. The importance of the design a lgorithm and the phase-encoding geometry of the diffractive element is discussed with regard to the performance of both on-and off-axis reco nstruction, notably for pixelated gratings. A new phase-encoding schem e is presented that results in an increase of the diffraction efficien cy for the off-axis case. (C) 1997 Optical Society of America.
