Abstract: A method to identify the azimuthal index of vortices and the radial parameter of axicons, as well as their associated spatial frequencies, is presented. These constructive parameters are employed to design parallel superimposed computer-generated holograms… read more here.

Abstract: Diffractive optics elements have exhibited many novel characteristics through various methods of employing Pancharatnam-Berry, or geometric, phase. One geometric-phase hologram (GPH) subset, consisting of a π-difference binary sampling, shows polarization-independent properties that are not present… read more here.
