Paper Abstract

Error-diffusion computer-generated holograms (CGHs) are extended to allow the use of multilevels (rather than the conventional binary 0,1 values) and to phase modulation (to improve efficiency). These new CGHs allow high accuracy and reduced space-bandwidth-product transfer functions. CGHs for optical processing operations are described and laboratory data are included.
