    • openAccess   Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone 

      Peters, Eduardo; Funes, Gustavo; Martínez-León, Lluís; Tajahuerce, Enrique MDPI (2022-07-09)
      Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the vortex distribution. However, there are still discrepancies in the value of the vortex strength of FVBs at the far field. In ...

    • closedAccess   Real-time acquisition of complex optical fields by binary amplitude modulation 

      Peters, Eduardo; Clemente, Pere; Salvador Balaguer, Eva; Tajahuerce, Enrique; Andrés, Pedro; Pérez, Darío G.; Lancis, Jesús Optical Society of America (2017)
      We describe, through simulations and experiments, a real-time wavefront acquisition technique using random binary amplitude masks and an iterative phase retrieval algorithm based on the Fresnel propagator. By using a digital ...
