The research is directed toward novel approaches to wavefront synthesis         and reconstruction by means of digital diffractive elements to produce          very high performance computer-generated holograms with a minimum of            speckle noise.  A hologram is a synthetically reconstructed image               generated by computer processing of laser-generated views of an object.         Holograms are being used in commercial applications such as                     nondestructive testing, heads-up displays, information storage, and             testing of aspherical optics.  The list of applications would grow              appreciably if improved, reliable holograms and better methods of               generation were available.  In this research effort, the principal              investigators are utilizing very high resolution digital diffractive            elements (DDE) to perform wavefront synthesis and manipulation to do            speckle suppression and make high performance computer-generated                holograms.
