Generation of Perfect Optical Vortices by Using a Transmission Liquid Crystal Spatial Light Modulator

open access: yesInternational Journal of Optics, Volume 2017, Issue 1, 2017., 2017
We have experimentally created perfect optical vortices by the Fourier transformation of holographic masks with combination of axicons and spiral functions, which are displayed on a transmission liquid crystal spatial light modulator. We showed theoretically that the size of the annular vortex in the Fourier plane is independent of the spiral phase ...

Electoral manipulation and postelectoral protests in Latin America

open access: yesLatin American Policy, Volume 15, Issue 3, Page 362-371, September 2024.

The political science literature has traditionally expected that election manipulation can lead to postelection demonstrations, but the research has not dealt much with how the elections were manipulated. This study aims to fill this gap.
