Abstract
Current liquid crystal technology allows the production of microdisplays (LCD, Liquid Crystal Displays), with a typical size of 1 or 2 square centimetres, and with resolutions in the order of 1000x1000 pixels. These displays can be used in the field of diffractive optics for the generation of novel programmable optical diffractive elements. Researchers from the UAB Department of Physics have collaborated with researchers from the University Miguel Hernández of Elche (Spain), University of Buenos Aires (Argentina) and University de La Frontera (Chile), in the study of a simple polarization diffractive element that , in the diffraction field, generates a periodic structure of polarization vortices.
