    Applications of spatial light modulators in speckle interferometry
    (SPIE-INT SOC OPTICAL ENGINEERING, 2012-01-01) Bodendorfer, T.; Restrepo, R.; Belenguer, T.; Koch, A.W.; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica Aplicada
    High resolution spatial light modulators (SLM) have been used in many different ways during the last years. Regarding speckle interferometry, different applications can be realized by integrating SLMs in interferometric setup. In this work the influence of a liquid crystal based phase-only SLM on the measurement quality concerning deformation and shape measurement using two wavelengths is discussed. © 2012 Copyright SPIE.

    Improving on-axis optical vortex generation by transmissive spatial light modulator using coherent phase diversity
    (OSA - The Optical Society, 2016-01-01) Cuartas-Vélez, C.; Restrepo, R.; Echeverri-Chacón, S.; Uribe-Patarroyo, N.; Universidad EAFIT. Departamento de Ciencias Básicas; Óptica Aplicada
    We present a modification of numerical optimization coherent phase diversity in order to detect and correct undesired effects of non-linear and incomplete phase modulation of transmissive spatial light modulators for on-axis optical vortices. © OSA 2016.
