    • openAccess   Diffraction-Based Phase Calibration of Spatial Light Modulators With Binary Phase Fresnel Lenses 

      Mendoza-Yero, Omel; Mínguez-Vega, Gladys; Martínez-León, Lluís; Carbonell Leal, Miguel; Fernández Alonso, Mercedes; Doñate-Buendía, Carlos; Pérez Vizcaíno, Jorge; Lancis, Jesús IEEE (2016)
      We propose a simple and robust method to determine the calibration function of phase-only spatial light modulators (SLMs). The proposed method is based on the codification of binary phase Fresnel lenses (BPFLs) onto an ...

    • openAccess   Femtosecond laser settings for optimal bracket bonding to zirconia 

      García-Sanz, Verónica; Paredes-Gallardo, Vanessa; Bellot-Arcís, Carlos; Martínez-León, Lluís; Torres-Mendieta, Rafael; Montero, Javier; Albadalejo, Alberto Springer Verlag (2018)
      Bonding orthodontic brackets to ceramic materials is a challenging procedure; femtosecond (FS) laser conditioning could provide improved results, but the ideal settings for effective bracket-zirconia bonding have never ...

    • openAccess   High sampling rate single-pixel digital holography system employing a DMD and phase-encoded patterns 

      González, Humberto; Martínez-León, Lluís; Soldevila, Fernando; Araiza Esquivel, María A.; Lancis, Jesús; Tajahuerce, Enrique Optical Society of America (2018)
      A single-pixel digital holography system with phase-encoded illumination using a digital micromirror device (DMD) as a spatial light modulator (SLM) is presented. The enhanced switching rate of DMDs, far exceeding the ...

    • openAccess   Phase calibration of spatial light modulators by means of Fresnel images 

      Martínez-León, Lluís; Jaroszewicz, Z.; Kołodziejczyk, A.; Durán, Vicente; Tajahuerce, Enrique; Lancis, Jesús Institute of Physics (2009)
      Reliable application of spatial light modulators (SLMs) as programmable diffractive optical elements requires a thorough calibration. In this paper, we propose a method for calibrating SLMs based on the evaluation of ...

    • openAccess   Poincaré-sphere representation of phase-mostly twisted nematic liquid crystal spatial light modulators 

      Durán, Vicente; Clemente Pesudo, Pedro Javier; Martínez-León, Lluís; Climent, Vicent; Lancis, Jesús Institute of Physics (2009)
      We establish necessary conditions in order to design a phase-only wave front modulation system from a liquid crystal display. These conditions determine the dependence of the polarization state of the light emerging from ...

    • openAccess   Spatial-chirp compensation in dynamical holograms reconstructed with ultrafast lasers 

      Martínez-León, Lluís; Clemente Pesudo, Pedro Javier; Tajahuerce, Enrique; Mínguez-Vega, Gladys; Mendoza-Yero, Omel; Fernández Alonso, Mercedes; Lancis, Jesús; Climent, Vicent; Andrés, Pedro American Institute of Physics (2008)
      A computer generated hologram (CGH) reconstructed with a sub-100-fs laser pulse at the focal plane of a conventional refractive lens experiences a large amount of spatial chirp. We report the shaping of a 12 fs laser pulsed ...

    • openAccess   Synthetic aperture single-exposure on-axis digital holography 

      Martínez-León, Lluís; Javidi, Bahram Optical Society of America (2008)
      We present a system for reconstructing single-exposure on-line (SEOL) digital holograms with improved resolution using a synthetic aperture. Several recordings are made in order to compose the synthetic aperture, shifting ...

    • openAccess   Use of polar decomposition of Mueller matrices for optimizing the phase response of a liquid-crystal- on-silicon display 

      Martínez-León, Lluís; Clemente Pesudo, Pedro Javier; Durán, Vicente; Climent, Vicent; Tajahuerce, Enrique; Lancis, Jesús Optical Society of America (2008)
      We provide experimental measurement of the Mueller matrices corresponding to an on-state liquid-crystal-on-silicon display as a function of the addressed voltage. The polar decomposition of the Mueller matrices determines ...

    • openAccess   Valencian Network of Educational Innovation in Optics 

      Pons Martí, Amparo; Barreiro, J.C.; Fernández Alonso, Mercedes; Martínez-León, Lluís; Giménez, M.H.; Monsoriu, Juan A. Universitat Politècnica de València (2014)
      The Valencian Network of Educational Innovation in Optics consists of three groups from the Universitat de València, Universitat Jaume I, and Universitat Politècnica de València. The participants in the network present an ...
